924ed16386 ast2400: add SPI flash slaves
Each controller on the ast2400 has a memory range on which it maps its
flash module slaves. Each slave is assigned a memory segment for its
mapping that can be changed at bootime with the Segment Address
Register. This is not supported in the current implementation so we
are using the defaults provided by the specs.

Each SPI flash slave can then be accessed in two modes: Command and
User. When in User mode, accesses to the memory segment of the slaves
are translated in SPI transfers. When in Command mode, the HW
generates the SPI commands automatically and the memory segment is
accessed as if doing a MMIO. Other SPI controllers call that mode
linear addressing mode.

For this purpose, we are adding below each crontoller an array of
structs gathering for each SPI flash module, a segment rank, a
MemoryRegion to handle the memory accesses and the associated SPI
slave device, which should be a m25p80.

Only the User mode is supported for now but we are preparing ground
for the Command mode. The framework is sufficient to support Linux.

7c1c69bca4 ast2400: add SMC controllers (FMC and SPI)
The Aspeed AST2400 soc includes a static memory controller for the BMC
which supports NOR, NAND and SPI flash memory modules. This controller
has two modes : the SMC for the legacy interface which supports only
one module and the FMC for the new interface which supports up to five
modules. The AST2400 also includes a SPI only controller used for the
host firmware, commonly called BIOS on Intel. It can be used in three
mode : a SPI master, SPI slave and SPI pass-through

Below is the initial framework for the SMC controller (FMC mode only)
and the SPI controller: the sysbus object, MMIO for registers
configuration and controls. Each controller has a SPI bus and a
configurable number of CS lines for SPI flash slaves.

The differences between the controllers are small, so they are
abstracted using indirections on the register numbers.

Only SPI flash modules are supported.

b7f480c3f6 m25p80: change cur_addr to 32 bit integer
The maximum amount of storage that can be addressed by the m25p80 command
set is 4 GiB.  However, cur_addr is currently a 64-bit integer.  To avoid
further problems related to sign extension of signed 32-bit integer
expressions, change cur_addr to a 32 bit integer.  Preserve migration
format by adding a dummy 4-byte field in place of the (big-endian)
high four bytes in the formerly 64-bit cur_addr field.

b68cb06093 m25p80: avoid out of bounds accesses
s->cur_addr can be made to point outside s->storage, either by
writing a value >= 128 to s->ear (because s->ear * MAX_3BYTES_SIZE
is a signed integer and sign-extends into the 64-bit cur_addr),
or just by writing an address beyond the size of the flash being
emulated.  Avoid the sign extension to make the code cleaner, and
on top of that mask s->cur_addr to s->size.

cace7b801d m25p80: do not put iovec on the stack
When doing a read-modify-write cycle, QEMU uses the iovec after returning
from blk_aio_pwritev.  m25p80 puts the iovec on the stack of blk_aio_pwritev's
caller, which causes trouble in this case.  This has been a problem
since commit 243e6f6 ("m25p80: Switch to byte-based block access",
2016-05-12) started doing writes at a smaller granularity than 512 bytes.
In principle however it could have broken before when using -drive
if=mtd,cache=none on a disk with 4K native sectors.

684204593d register: Define REG and FIELD macros
Define some macros that can be used for defining registers and fields.

The REG32 macro will define A_FOO, for the byte address of a register
as well as R_FOO for the uint32_t[] register number (A_FOO / 4).

The FIELD macro will define FOO_BAR_MASK, FOO_BAR_SHIFT and
FOO_BAR_LENGTH constants for field BAR in register FOO.

Finally, there are some shorthand helpers for extracting/depositing
fields from registers based on these naming schemes.

Usage can greatly reduce the verbosity of device code.

The deposit and extract macros (eg FIELD_EX32, FIELD_DP32  etc.) can be
used to generate extract and deposits without any repetition of the name
stems.

1599121b57 register: Add Register API
This API provides some encapsulation of registers and factors out some
common functionality to common code. Bits of device state (usually MMIO
registers) often have all sorts of access restrictions and semantics
associated with them. This API allows you to define what those
restrictions are on a bit-by-bit basis.

Helper functions are then used to access the register which observe the
semantics defined by the RegisterAccessInfo struct.

Some features:
Bits can be marked as read_only (ro field)
Bits can be marked as write-1-clear (w1c field)
Bits can be marked as reserved (rsvd field)
Reset values can be defined (reset)
Bits can be marked clear on read (cor)
Pre and post action callbacks can be added to read and write ops
Verbose debugging info can be enabled/disabled

Useful for defining device register spaces in a data driven way. Cuts
down on a lot of the verbosity and repetition in the switch-case blocks
in the standard foo_mmio_read/write functions.

Also useful for automated generation of device models from hardware
design sources.

5d636e21c4 hw/arm/virt: mark the PCIe host controller as DMA coherent in the DT
Since QEMU performs cacheable accesses to guest memory when doing DMA
as part of the implementation of emulated PCI devices, guest drivers
should use cacheable accesses as well when running under KVM. Since this
essentially means that emulated PCI devices are DMA coherent, set the
'dma-coherent' DT property on the PCIe host controller DT node.

This brings the DT description into line with the ACPI description,
which already marks the PCI bridge as cache coherent (see commit
bc64b96c98).

019a3edbb2: ("virtio: make features 64bit

self announcement and guest offloads before the second copy including
high feature bits is loaded.  This means that self announcement, control
vq and guest offloads are all broken after migration.

Fix it up by loading low feature bits: somewhat ugly since high and low
bits become out of sync temporarily, but seems unavoidable for
compatibility.  The right thing to do for new features is probably to
test the host features, anyway.

97a83ec3a9 piix: Set I440FXState member pci_info.w32 in one place
Range pci_info.w32 records the location of the PCI hole.

It's initialized to empty when QOM zeroes I440FXState.  That's a fine
value for a still unknown PCI hole.

i440fx_init() sets pci_info.w32.begin = below_4g_mem_size.  Changes
the PCI hole from empty to [below_4g_mem_size, UINT64_MAX].  That's a
bogus value.

i440fx_pcihost_initfn() sets pci_info.end = IO_APIC_DEFAULT_ADDRESS.
Since i440fx_init() ran already, this changes the PCI hole to
[below_4g_mem_size, IO_APIC_DEFAULT_ADDRESS-1].  That's the correct
value.

Setting the bounds of the PCI hole in two separate places is
confusing, and begs the question whether the bogus intermediate value
could be used by something, or what would happen if we somehow managed
to realize an i440FX device without having run the board init function
i440fx_init() first.

Avoid the confusion by setting the (constant) upper bound along with
the lower bound in i440fx_init().

At first Q35 will support only intel-iommu to be added this way,
however the command line will support all sysbus devices.

Mark with 'cannot_instantiate_with_device_add_yet' the ones
causing immediate problems (e.g. crashes).

5ec7d09818 xen: fix ram init regression
Commit "8156d48 pc: allow raising low memory via max-ram-below-4g
option" causes a regression on xen, because it uses a different
memory split.

This patch initializes max-ram-below-4g to zero and leaves the
initialization to the memory initialization functions.  That way
they can pick different default values (max-ram-below-4g is zero
still) or use the user supplied value (max-ram-below-4g is non-zero).

Also skip the whole ram split calculation on Xen.  xen_ram_init()
does its own split calculation anyway so it is superfluous, also
this way xen_ram_init can actually see whenever max-ram-below-4g
is zero or not.

0c16c056a4 crypto: switch hash code to use nettle/gcrypt directly
Currently the internal hash code is using the gnutls hash APIs.
GNUTLS in turn is wrapping either nettle or gcrypt. Not only
were the GNUTLS hash APIs not added until GNUTLS 2.9.10, but
they don't expose support for all the algorithms QEMU needs
to use with LUKS.

Address this by directly wrapping nettle/gcrypt in QEMU and
avoiding GNUTLS's extra layer of indirection. This gives us
support for hash functions on a much wider range of platforms
and opens up ability to support more hash functions. It also
avoids a GNUTLS bug which would not correctly handle hashing
of large data blocks if int != size_t.

8b7cdba386 crypto: fix handling of iv generator hash defaults
When opening an existing LUKS volume, if the iv generator is
essiv, then the iv hash algorithm is mandatory to provide. We
must report an error if it is omitted in the cipher mode spec,
not silently default to hash 0 (md5).  If the iv generator is
not essiv, then we explicitly ignore any iv hash algorithm,
rather than report an error, for compatibility with dm-crypt.

When creating a new LUKS volume, if the iv generator is essiv
and no iv hsah algorithm is provided, we should default to
using the sha256 hash.

4e04ab6a63 bios: Add fast variant of SeaBIOS for use with -kernel on x86.
This commit adds a fast variant of SeaBIOS called 'bios-fast.bin'.

It's designed to be the fastest (also the smallest, but that's not the
main aim) SeaBIOS that is just enough to boot a Linux kernel using the
-kernel option on i686 and x86_64.

This commit does not modify the -kernel option to use this.  You have
to specify it by doing something like this:

  -kernel vmlinuz -bios bios-fast.bin

e5857062a6 slirp: Remove superfluous memset() calls from the TFTP code
Commit fad7fb9ccd  ("Add IPv6 support to the TFTP code")
refactored some common code for preparing the mbuf into a new
function called tftp_prep_mbuf_data(). One part of this common
code is to do a "memset(m->m_data, 0, m->m_size);" for the related
buffer first. However, at two spots, the memset() was not removed
from the calling function, so it currently done twice in these code
paths. Thus let's delete these superfluous memsets in the calling
functions now.
