757e99b1eb riscv/boot: Add a missing header include
As the functions declared in this header use the symbol_fn_t
typedef itself declared in "hw/loader.h", we need to include
it here to make the header file self-contained.

Headers should be self-contained, and one shouldn't have to

0911a60c76 ppc/spapr: Add hotremovable flag on DIMM LMBs on drmem_v2
On reboot, all memory that was previously added using object_add and
device_add is placed in this DIMM area.

The new SPAPR_LMB_FLAGS_HOTREMOVABLE flag helps Linux to put this memory in
the correct memory zone, so no unmovable allocations are made there,
allowing the object to be easily hot-removed by device_del and
object_del.

This new flag was accepted in Power Architecture documentation.

This reverts commit f79081b4b7.

Patch has broken byteorder handling: RAMFBCfg fields are in bigendian
byteorder, the reset function doesn't care so native byteorder is used
instead.  Given this went unnoticed so far the feature is obviously
unused, so just revert the patch.

b69c3c21a5 qdev: Unrealize must not fail
Devices may have component devices and buses.

Device realization may fail.  Realization is recursive: a device's
realize() method realizes its components, and device_set_realized()
realizes its buses (which should in turn realize the devices on that
bus, except bus_set_realized() doesn't implement that, yet).

When realization of a component or bus fails, we need to roll back:
unrealize everything we realized so far.  If any of these unrealizes
failed, the device would be left in an inconsistent state.  Must not
happen.

device_set_realized() lets it happen: it ignores errors in the roll
back code starting at label child_realize_fail.

Since realization is recursive, unrealization must be recursive, too.
But how could a partly failed unrealize be rolled back?  We'd have to
re-realize, which can fail.  This design is fundamentally broken.

device_set_realized() does not roll back at all.  Instead, it keeps
unrealizing, ignoring further errors.

It can screw up even for a device with no buses: if the lone
dc->unrealize() fails, it still unregisters vmstate, and calls
listeners' unrealize() callback.

bus_set_realized() does not roll back either.  Instead, it stops
unrealizing.

Fortunately, no unrealize method can fail, as we'll see below.

To fix the design error, drop parameter @errp from all the unrealize
methods.

Any unrealize method that uses @errp now needs an update.  This leads
us to unrealize() methods that can fail.  Merely passing it to another
unrealize method cannot cause failure, though.  Here are the ones that
do other things with @errp:

* virtio_serial_device_unrealize()

  Fails when qbus_set_hotplug_handler() fails, but still does all the
  other work.  On failure, the device would stay realized with its
  resources completely gone.  Oops.  Can't happen, because
  qbus_set_hotplug_handler() can't actually fail here.  Pass
  &error_abort to qbus_set_hotplug_handler() instead.

* hw/ppc/spapr_drc.c's unrealize()

  Fails when object_property_del() fails, but all the other work is
  already done.  On failure, the device would stay realized with its
  vmstate registration gone.  Oops.  Can't happen, because
  object_property_del() can't actually fail here.  Pass &error_abort
  to object_property_del() instead.

* spapr_phb_unrealize()

  Fails and bails out when remove_drcs() fails, but other work is
  already done.  On failure, the device would stay realized with some
  of its resources gone.  Oops.  remove_drcs() fails only when
  chassis_from_bus()'s object_property_get_uint() fails, and it can't
  here.  Pass &error_abort to remove_drcs() instead.

Therefore, no unrealize method can fail before this patch.

device_set_realized()'s recursive unrealization via bus uses
object_property_set_bool().  Can't drop @errp there, so pass
&error_abort.

We similarly unrealize with object_property_set_bool() elsewhere,
always ignoring errors.  Pass &error_abort instead.

Several unrealize methods no longer handle errors from other unrealize
methods: virtio_9p_device_unrealize(),
virtio_input_device_unrealize(), scsi_qdev_unrealize(), ...
Much of the deleted error handling looks wrong anyway.

One unrealize methods no longer ignore such errors:
usb_ehci_pci_exit().

Several realize methods no longer ignore errors when rolling back:
v9fs_device_realize_common(), pci_qdev_unrealize(),
spapr_phb_realize(), usb_qdev_realize(), vfio_ccw_realize(),
virtio_device_realize().

558b9d8640 ACPI: Record Generic Error Status Block(GESB) table
kvm_arch_on_sigbus_vcpu() error injection uses source_id as
index in etc/hardware_errors to find out Error Status Data
Block entry corresponding to error source. So supported source_id
values should be assigned here and not be changed afterwards to
make sure that guest will write error into expected Error Status
Data Block.

Before QEMU writes a new error to ACPI table, it will check whether
previous error has been acknowledged. If not acknowledged, the new
errors will be ignored and not be recorded. For the errors section
type, QEMU simulate it to memory section error.

a08a64627b ACPI: Record the Generic Error Status Block address
Record the GHEB address via fw_cfg file, when recording
a error to CPER, it will use this address to find out
Generic Error Data Entries and write the error.

In order to avoid migration failure, make hardware
error table address to a part of GED device instead
of global variable, then this address will be migrated
to target QEMU.

205cc75dee ACPI: Build Hardware Error Source Table
This patch builds Hardware Error Source Table(HEST) via fw_cfg blobs.
Now it only supports ARMv8 SEA, a type of Generic Hardware Error
Source version 2(GHESv2) error source. Afterwards, we can extend
the supported types if needed. For the CPER section, currently it
is memory section because kernel mainly wants userspace to handle
the memory errors.

This patch follows the spec ACPI 6.2 to build the Hardware Error
Source table. For more detailed information, please refer to
document: docs/specs/acpi_hest_ghes.rst

build_ghes_hw_error_notification() helper will help to add Hardware
Error Notification to ACPI tables without using packed C structures
and avoid endianness issues as API doesn't need explicit conversion.

The CAS reboot flag is false by default and all the locations that
could set it to true have been dropped. This means that all code
blocks depending on the flag being set is dead code and the other
code blocks should be executed always.

Just do that and drop the now uneeded CAS reboot flag. Fix a

91067db1ab spapr/cas: Separate CAS handling from rebuilding the FDT
At the moment "ibm,client-architecture-support" ("CAS") is implemented
in SLOF and QEMU assists via the custom H_CAS hypercall which copies
an updated flatten device tree (FDT) blob to the SLOF memory which
it then uses to update its internal tree.

When we enable the OpenFirmware client interface in QEMU, we won't need
to copy the FDT to the guest as the client is expected to fetch
the device tree using the client interface.

This moves FDT rebuild out to a separate helper which is going to be
called from the "ibm,client-architecture-support" handler and leaves
writing FDT to the guest in the H_CAS handler.

This should not cause any behavioral change.

5c94b82662 nvdimm: Use configurable ACPI IO base and size
This patch makes IO base and size configurable to create NPIO AML for
ACPI NFIT. Since a different architecture like AArch64 does not use
port-mapped IO, a configurable IO base is required to create correct
mapping of ACPI IO address and size.

a1ecb43818 elf_ops: Don't try to g_mapped_file_unref(NULL)
Calling g_mapped_file_unref() on a NULL pointer is not valid, and
glib will assert if you try it.

$ qemu-system-arm -M virt -display none -device loader,file=/tmp/bad.elf
qemu-system-arm: -device loader,file=/tmp/bad.elf: GLib: g_mapped_file_unref: assertion 'file != NULL' failed

(One way to produce an ELF file that fails like this is to copy just
the first 16 bytes of a valid ELF file; this is sufficient to fool
the code in load_elf_ram_sym() into thinking it's an ELF file and
calling load_elf32() or load_elf64().)

The failure-exit path in load_elf can be reached from various points
in execution, and for some of those we haven't yet called
g_mapped_file_new_from_fd().  Add a condition to the unref call so we
only call it if we successfully created the GMappedFile to start with.

This will fix the assertion; for the specific case of the generic
loader it will then fall back from "guess this is an ELF file" to
"maybe it's a uImage or a hex file" and eventually to "just load as
a raw data file".

b636db306e hw/char/cadence_uart: add clock support
Switch the cadence uart to multi-phase reset and add the
reference clock input.

The input clock frequency is added to the migration structure.

The reference clock controls the baudrate generation. If it disabled,
any input characters and events are ignored.

If this clock remains unconnected, the uart behaves as before
(it default to a 50MHz ref clock).

Introduce a function and macro helpers to setup several clocks
in a device from a static array description.

An element of the array describes the clock (name and direction) as
well as the related callback and an optional offset to store the
created object pointer in the device state structure.

The array must be terminated by a special element QDEV_CLOCK_END.

This is based on the original work of Frederic Konrad.

4cba075efe hw/core/clock: introduce clock object
This object may be used to represent a clock inside a clock tree.

A clock may be connected to another clock so that it receives update,
through a callback, whenever the source/parent clock is updated.

Although only the root clock of a clock tree controls the values
(represented as periods) of all clocks in tree, each clock holds
a local state containing the current value so that it can be fetched
independently. It will allows us to fullfill migration requirements
by migrating each clock independently of others.

This is based on the original work of Frederic Konrad.

c8aeef3aed nrf51: Fix last GPIO CNF address
NRF51_GPIO_REG_CNF_END doesn't actually refer to the start of the last
valid CNF register: it's referring to the last byte of the last valid
CNF register.

This hasn't been a problem up to now, as current implementation in
memory.c turns an unaligned 4-byte read from 0x77f to a single byte read
and the qtest only looks at the least-significant byte of the register.

But when running with patches which fix unaligned accesses in memory.c,
the qtest breaks.

Considering NRF51 doesn't support unaligned accesses, the simplest fix
is to actually set NRF51_GPIO_REG_CNF_END to the start of the last valid
CNF register: 0x77c.

02777ac303 hw/riscv: Add optional symbol callback ptr to riscv_load_firmware()
This patch adds an optional function pointer, "sym_cb", to
riscv_load_firmware() which provides the possibility to access
the symbol table during kernel loading.

The pointer is ignored, if supplied with flat (non-elf) firmware image.

The Spike board requires it locate the HTIF symbols from firmware ELF
passed via "-bios" option.

3ca109c3f8 riscv/sifive_u: Add a serial property to the sifive_u machine
At present the board serial number is hard-coded to 1, and passed
to OTP model during initialization. Firmware (FSBL, U-Boot) uses
the serial number to generate a unique MAC address for the on-chip
ethernet controller. When multiple QEMU 'sifive_u' instances are
created and connected to the same subnet, they all have the same
MAC address hence it creates a unusable network.

A new "serial" property is introduced to specify the board serial
number. When not given, the default serial number 1 is used.

0f73c5b30b s390x: protvirt: SCLP interpretation
SCLP for a protected guest is done over the SIDAD, so we need to use
the s390_cpu_pv_mem_* functions to access the SIDAD instead of guest
memory when reading/writing SCBs.

To not confuse the sclp emulation, we set 0x4000 as the SCCB address,
since the function that injects the sclp external interrupt would
reject a zero sccb address.

The unpack facility provides the means to setup a protected guest. A
protected guest cannot be introspected by the hypervisor or any
user/administrator of the machine it is running on.

Protected guests are encrypted at rest and need a special boot
mechanism via diag308 subcode 8 and 10.

Code 8 sets the PV specific IPLB which is retained separately from
those set via code 5.

Code 10 is used to unpack the VM into protected memory, verify its
integrity and start it.

f26740c61a smbus: Fix spd_data_generate() error API violation
The Error ** argument must be NULL, &error_abort, &error_fatal, or a
pointer to a variable containing NULL.  Passing an argument of the
latter kind twice without clearing it in between is wrong: if the
first call sets an error, it no longer points to NULL for the second
call.

spd_data_generate() can pass @errp to error_setg() more than once when
it adjusts both memory size and type.  Harmless, because no caller
passes anything that needs adjusting.  Until the previous commit,
sam460ex passed types that needed adjusting, but not sizes.

spd_data_generate()'s contract is rather awkward:

    If everything's fine, return non-null and don't set an error.

    Else, if memory size or type need adjusting, return non-null and
    set an error describing the adjustment.

    Else, return null and set an error reporting why no data can be
    generated.

Its callers treat the error as a warning even when null is returned.
They don't create the "smbus-eeprom" device then.  Suspicious.

Since the previous commit, only "everything's fine" can actually
happen.  Drop the unused code and simplify the callers.  This gets rid
of the error API violation.

394f0f72fd fw_cfg: Migrate ACPI table mr sizes separately
Any sub-page size update to ACPI MRs will be lost during
migration, as we use aligned size in ram_load_precopy() ->
qemu_ram_resize() path. This will result in inconsistency in
FWCfgEntry sizes between source and destination. In order to avoid
this, save and restore them separately during migration.

Up until now, this problem may not be that relevant for x86 as both
ACPI table and Linker MRs gets padded and aligned. Also at present,
qemu_ram_resize() doesn't invoke callback to update FWCfgEntry for
unaligned size changes. But since we are going to fix the
qemu_ram_resize() in the subsequent patch, the issue may become
more serious especially for RSDP MR case.

Moreover, the issue will soon become prominent in arm/virt as well
where the MRs are not padded or aligned at all and eventually have
acpi table changes as part of future additions like NVDIMM hot-add
feature.

Commit e2392d4395 ("ppc/pnv: Create BMC devices at machine init")
introduced default BMC devices which can be a problem when the same
devices are defined on the command line with :

  -device ipmi-bmc-sim,id=bmc0 -device isa-ipmi-bt,bmc=bmc0,irq=10

QEMU fails with :

  qemu-system-ppc64: error creating device tree: node: FDT_ERR_EXISTS

Use defaults_enabled() when creating the default BMC devices to let
the user provide its own BMC devices using '-nodefaults'. If no BMC
device are provided, output a warning but let QEMU run as this is a
supported configuration. However, when multiple BMC devices are
defined, stop QEMU with a clear error as the results are unexpected.

5c30ef937f vl/s390x: fixup ram sizes for compat machines
Older QEMU versions did fixup the ram size to match what can be reported
via sclp. We need to mimic this behaviour for machine types 4.2 and
older to not fail on inbound migration for memory sizes that do not fit.
Old machines with proper aligned memory sizes are not affected.

Alignment table:
 VM size (<=) | Alignment
--------------------------
      1020M   |     1M
      2040M   |     2M
      4080M   |     4M
      8160M   |     8M
     16320M   |    16M
     32640M   |    32M
     65280M   |    64M
    130560M   |   128M
    261120M   |   256M
    522240M   |   512M
   1044480M   |     1G
   2088960M   |     2G
   4177920M   |     4G
   8355840M   |     8G

Suggested action is to replace unaligned -m value with a suitable
aligned one or if a change to a newer machine type is possible, use a
machine version >= 5.0.

A future version might remove the compatibility handling.

For machine types >= 5.0 we can simply use an increment size of 1M and
use the full range of increment number which allows for all possible
memory sizes. The old limitation of having a maximum of 1020 increments
was added for standby memory, which we no longer support. With that we
can now support even weird memory sizes like 10001234 MB.

As we no longer fixup maxram_size as well, make other users use ram_size
instead. Keep using maxram_size when setting the maximum ram size in KVM,
as that will come in handy in the future when supporting memory hotplug
(in contrast, storage keys and storage attributes for hotplugged memory
will have to be migrated per RAM block in the future).

7568b20555 hw/386: Add EPYC mode topology decoding functions
These functions add support for building EPYC mode topology given the smp
details like numa nodes, cores, threads and sockets.

The new apic id decoding is mostly similar to current apic id decoding
except that it adds a new field node_id when numa configured. Removes all
the hardcoded values. Subsequent patches will use these functions to build
the topology.

Following functions are added.
apicid_llc_width_epyc
apicid_llc_offset_epyc
apicid_pkg_offset_epyc
apicid_from_topo_ids_epyc
x86_topo_ids_from_idx_epyc
x86_topo_ids_from_apicid_epyc
x86_apicid_from_cpu_idx_epyc

The topology details are available in Processor Programming Reference (PPR)
for AMD Family 17h Model 01h, Revision B1 Processors. The revision guides are
available from the bugzilla Link below.

9e58f17270 fdc/i8257: implement verify transfer mode
While working on the Tulip driver i tried to write some Teledisk images to
a floppy image which didn't work. Turned out that Teledisk checks the written
data by issuing a READ command to the FDC but running the DMA controller
in VERIFY mode. As we ignored the DMA request in that case, the DMA transfer
never finished, and Teledisk reported an error.

The i8257 spec says about verify transfers:

3) DMA verify, which does not actually involve the transfer of data. When an
8257 channel is in the DMA verify mode, it will respond the same as described
for transfer operations, except that no memory or I/O read/write control signals
will be generated.

Hervé proposed to remove all the dma_mode_ok stuff from fdc to have a more
clear boundary between DMA and FDC, so this patch also does that.

781c67ca55 cpu: Use DeviceClass reset instead of a special CPUClass reset
The CPUClass has a 'reset' method.  This is a legacy from when
TYPE_CPU used not to inherit from TYPE_DEVICE.  We don't need it any
more, as we can simply use the TYPE_DEVICE reset.  The 'cpu_reset()'
function is kept as the API which most places use to reset a CPU; it
is now a wrapper which calls device_cold_reset() and then the
tracepoint function.

This change should not cause CPU objects to be reset more often
than they are at the moment, because:
 * nobody is directly calling device_cold_reset() or
   qdev_reset_all() on CPU objects
 * no CPU object is on a qbus, so they will not be reset either
   by somebody calling qbus_reset_all()/bus_cold_reset(), or
   by the main "reset sysbus and everything in the qbus tree"
   reset that most devices are reset by

Note that this does not change the need for each machine or whatever
to use qemu_register_reset() to arrange to call cpu_reset() -- that
is necessary because CPU objects are not on any qbus, so they don't
get reset when the qbus tree rooted at the sysbus bus is reset, and
this isn't being changed here.

All the changes to the files under target/ were made using the
included Coccinelle script, except:

(1) the deletion of the now-inaccurate and not terribly useful
"CPUClass::reset" comments was done with a perl one-liner afterwards:
  perl -n -i -e '/ CPUClass::reset/ or print' target/*/*.c

(2) this bit of the s390 change was done by hand, because the
Coccinelle script is not sophisticated enough to handle the
parent_reset call being inside another function:

| @@ -96,8 +96,9 @@ static void s390_cpu_reset(CPUState *s, cpu_reset_type type)
|     S390CPU *cpu = S390_CPU(s);

4dba872219 spapr/rtas: Reserve space for RTAS blob and log
At the moment SLOF reserves space for RTAS and instantiates the RTAS blob
which is 20 bytes binary blob calling an hypercall. The rest of the RTAS
area is a log which SLOF has no idea about but QEMU does.

This moves RTAS sizing to QEMU and this overrides the size from SLOF.
The only remaining problem is that SLOF copies the number of bytes it
reserved (2KB for now) so QEMU needs to reserve at least this much;
SLOF will be fixed separately to check that rtas-size from QEMU is
enough for those 20 bytes for the H_RTAS hcall.

1052ab67f4 spapr: Don't clamp RMA to 16GiB on new machine types
In spapr_machine_init() we clamp the size of the RMA to 16GiB and the
comment saying why doesn't make a whole lot of sense.  In fact, this was
done because the real mode handling code elsewhere limited the RMA in TCG
mode to the maximum value configurable in LPCR[RMLS], 16GiB.

But,
 * Actually LPCR[RMLS] has been able to encode a 256GiB size for a very
   long time, we just didn't implement it properly in the softmmu
 * LPCR[RMLS] shouldn't really be relevant anyway, it only was because we
   used to abuse the RMOR based translation mode in order to handle the
   fact that we're not modelling the hypervisor parts of the cpu

We've now removed those limitations in the modelling so the 16GiB clamp no
longer serves a function.  However, we can't just remove the limit
universally: that would break migration to earlier qemu versions, where
the 16GiB RMLS limit still applies, no matter how bad the reasons for it
are.

So, we replace the 16GiB clamp, with a clamp to a limit defined in the
machine type class.  We set it to 16 GiB for machine types 4.2 and earlier,
but set it to 0 meaning unlimited for the new 5.0 machine type.

8897ea5a9f spapr: Don't attempt to clamp RMA to VRMA constraint
The Real Mode Area (RMA) is the part of memory which a guest can access
when in real (MMU off) mode.  Of course, for a guest under KVM, the MMU
isn't really turned off, it's just in a special translation mode - Virtual
Real Mode Area (VRMA) - which looks like real mode in guest mode.

The mechanics of how this works when using the hash MMU (HPT) put a
constraint on the size of the RMA, which depends on the size of the
HPT.  So, the latter part of spapr_setup_hpt_and_vrma() clamps the RMA
we advertise to the guest based on this VRMA limit.

There are several things wrong with this:
 1) spapr_setup_hpt_and_vrma() doesn't actually clamp, it takes the minimum
    of Node 0 memory size and the VRMA limit.  That will *often* work the
    same as clamping, but there can be other constraints on RMA size which
    supersede Node 0 memory size.  We have real bugs caused by this
    (currently worked around in the guest kernel)
 2) Some callers of spapr_setup_hpt_and_vrma() are in a situation where
    we're past the point that we can actually advertise an RMA limit to the
    guest
 3) But most fundamentally, the VRMA limit depends on host configuration
    (page size) which shouldn't be visible to the guest, but this partially
    exposes it.  This can cause problems with migration in certain edge
    cases, although we will mostly get away with it.

In practice, this clamping is almost never applied anyway.  With 64kiB
pages and the normal rules for sizing of the HPT, the theoretical VRMA
limit will be 4x(guest memory size) and so never hit.  It will hit with
4kiB pages, where it will be (guest memory size)/4.  However all mainstream
distro kernels for POWER have used a 64kiB page size for at least 10 years.

So, simply replace this logic with a check that the RMA we've calculated
based only on guest visible configuration will fit within the host implied
VRMA limit.  This can break if running HPT guests on a host kernel with
4kiB page size.  As noted that's very rare.  There also exist several
possible workarounds:
  * Change the host kernel to use 64kiB pages
  * Use radix MMU (RPT) guests instead of HPT
  * Use 64kiB hugepages on the host to back guest memory
  * Increase the guest memory size so that the RMA hits one of the fixed
    limits before the RMA limit.  This is relatively easy on POWER8 which
    has a 16GiB limit, harder on POWER9 which has a 1TiB limit.
  * Use a guest NUMA configuration which artificially constrains the RMA
    within the VRMA limit (the RMA must always fit within Node 0).

Previously, on KVM, we also temporarily reduced the rma_size to 256M so
that the we'd load the kernel and initrd safely, regardless of the VRMA
limit.  This was a) confusing, b) could significantly limit the size of
images we could load and c) introduced a behavioural difference between
KVM and TCG.  So we remove that as well.

ad334d89a6 spapr: Handle pending hot plug/unplug requests at CAS
If a hot plug or unplug request is pending at CAS, we currently trigger
a CAS reboot, which severely increases the guest boot time. This is
because SLOF doesn't handle hot plug events and we had no way to fix
the FDT that gets presented to the guest.

We can do better thanks to recent changes in QEMU and SLOF:

- we now return a full FDT to SLOF during CAS

- SLOF was fixed to correctly detect any device that was either added or
  removed since boot time and to update its internal DT accordingly.

The right solution is to process all pending hot plug/unplug requests
during CAS: convert hot plugged devices to cold plugged devices and
remove the hot unplugged ones, which is exactly what spapr_drc_reset()
does. Also clear all hot plug events that are currently queued since
they're no longer relevant.

Note that SLOF cannot currently populate hot plugged PCI bridges or PHBs
at CAS. Until this limitation is lifted, SLOF will reset the machine when
this scenario occurs : this will allow the FDT to be fully processed when
SLOF is started again (ie. the same effect as the CAS reboot that would
occur anyway without this patch).

880a7817c1 misc: Replace zero-length arrays with flexible array member (manual)
Description copied from Linux kernel commit from Gustavo A. R. Silva
(see [3]):

--v-- description start --v--

  The current codebase makes use of the zero-length array language
  extension to the C90 standard, but the preferred mechanism to
  declare variable-length types such as these ones is a flexible
  array member [1], introduced in C99:

  struct foo {
      int stuff;
      struct boo array[];
  };

  By making use of the mechanism above, we will get a compiler
  warning in case the flexible array does not occur last in the
  structure, which will help us prevent some kind of undefined
  behavior bugs from being unadvertenly introduced [2] to the
  Linux codebase from now on.

--^-- description end --^--

Do the similar housekeeping in the QEMU codebase (which uses
C99 since commit 7be41675f7).

All these instances of code were found with the help of the
following command (then manual analysis, without modifying
structures only having a single flexible array member, such
QEDTable in block/qed.h):

  git grep -F '[0];'

a80beb160d hw/arm/allwinner-h3: add Boot ROM support
A real Allwinner H3 SoC contains a Boot ROM which is the
first code that runs right after the SoC is powered on.
The Boot ROM is responsible for loading user code (e.g. a bootloader)
from any of the supported external devices and writing the downloaded
code to internal SRAM. After loading the SoC begins executing the code
written to SRAM.

This commits adds emulation of the Boot ROM firmware setup functionality
by loading user code from SD card in the A1 SRAM. While the A1 SRAM is
64KiB, we limit the size to 32KiB because the real H3 Boot ROM also rejects
sizes larger than 32KiB. For reference, this behaviour is documented
by the Linux Sunxi project wiki at:

2ac031d171 RISC-V Patches for the 5.0 Soft Freeze, Part 3
This pull request is almost entirely an implementation of the draft hypervisor
 extension.  This extension is still in draft and is expected to have
 incompatible changes before being frozen, but we've had good luck managing
 other RISC-V draft extensions in QEMU so far.
 
 Additionally, there's a fix to PCI addressing and some improvements to the
 M-mode timer.
 
 This boots linux and passes make check for me.

64bc77eb2c hw/nmi: Fix the NMI() macro, based on INTERFACE_CHECK()
There is no declaration of the 'NMI' type. INTERFACE_CHECK()
returns an abstract type (see commit aa1b35b975). The abstract
type corresponding to the TYPE_NMI interface is 'NMIState'.

11411489da arm_gic: Mask the un-supported priority bits
The GICv2 allows the implementation to implement a variable number
of priority bits; unimplemented bits in the priority registers
are read as zeros, writes ignored. We were previously always
implementing a full 8 bits of priority, which is allowed but not
what the real hardware typically does (which is usually to have
4 or 5 bits of priority).

Add a new device property to allow the number of implemented
property bits to be specified.
