This doesn't affect any machine types we currently support, because
for all of our machine types the RAM starts well below the 4GB
mark, but it does demonstrate that we're not currently writing
the device-tree properties quite as intended.

To fix it, we can change it to write these values to the dtb using a
type width matching #address-cells.  This is the intended size for
these dtb properties, and is how u-boot, for instance, writes them,
although in practice the Linux kernel will cope with them being any
width as long as they're big enough to fit the value.

503819a347 hw/arm: Convert TYPE_ARM_SMMUV3 to 3-phase reset
Convert the TYPE_ARM_SMMUV3 device to 3-phase reset.  The legacy
reset method doesn't do anything that's invalid in the hold phase, so
the conversion only requires changing it to a hold phase method, and
using the 3-phase versions of the "save the parent reset method and
chain to it" code.

3c1a7c4197 hw/arm: Convert TYPE_ARM_SMMU to 3-phase reset
Convert the TYPE_ARM_SMMU device to 3-phase reset.  The legacy method
doesn't do anything that's invalid in the hold phase, so the
conversion is simple and not a behaviour change.

Note that we must convert this base class before we can convert the
TYPE_ARM_SMMUV3 subclass -- transitional support in Resettable
handles "chain to parent class reset" when the base class is 3-phase
and the subclass is still using legacy reset, but not the other way
around.

94bc3b067e target/arm: Add Cortex-A55 CPU
The Cortex-A55 is one of the newer armv8.2+ CPUs; in particular
it supports the Privileged Access Never (PAN) feature. Add
a model of this CPU, so you can use a CPU type on the virt
board that models a specific real hardware CPU, rather than
having to use the QEMU-specific "max" CPU type.

0a0044b181 hw/arm/virt: build SMBIOS 19 table
Use the base_memmap to build the SMBIOS 19 table which provides the address
mapping for a Physical Memory Array (from spec [1] chapter 7.20).

This was present on i386 from commit c97294ec1b
("SMBIOS: Build aggregate smbios tables and entry point").

[1] https://www.dmtf.org/sites/default/files/standards/documents/DSP0134_3.5.0.pdf

The absence of this table is a breach of the specs and is
detected by the FirmwareTestSuite (FWTS), but it doesn't
cause any known problems for guest OSes.

6a48c64eec hw/arm/virt: Add properties to disable high memory regions
The 3 high memory regions are usually enabled by default, but they may
be not used. For example, VIRT_HIGH_GIC_REDIST2 isn't needed by GICv2.
This leads to waste in the PA space.

Add properties ("highmem-redists", "highmem-ecam", "highmem-mmio") to
allow users selectively disable them if needed. After that, the high
memory region for GICv3 or GICv4 redistributor can be disabled by user,
the number of maximal supported CPUs needs to be calculated based on
'vms->highmem_redists'. The follow-up error message is also improved
to indicate if the high memory region for GICv3 and GICv4 has been
enabled or not.

f40408a9fe hw/arm/virt: Add 'compact-highmem' property
After the improvement to high memory region address assignment is
applied, the memory layout can be changed, introducing possible
migration breakage. For example, VIRT_HIGH_PCIE_MMIO memory region
is disabled or enabled when the optimization is applied or not, with
the following configuration. The configuration is only achievable by
modifying the source code until more properties are added to allow
users selectively disable those high memory regions.

  pa_bits              = 40;
  vms->highmem_redists = false;
  vms->highmem_ecam    = false;
  vms->highmem_mmio    = true;

  # qemu-system-aarch64 -accel kvm -cpu host    \
    -machine virt-7.2,compact-highmem={on, off} \
    -m 4G,maxmem=511G -monitor stdio

  Region             compact-highmem=off         compact-highmem=on
  ----------------------------------------------------------------
  MEM                [1GB         512GB]        [1GB         512GB]
  HIGH_GIC_REDISTS2  [512GB       512GB+64MB]   [disabled]
  HIGH_PCIE_ECAM     [512GB+256MB 512GB+512MB]  [disabled]
  HIGH_PCIE_MMIO     [disabled]                 [512GB       1TB]

In order to keep backwords compatibility, we need to disable the
optimization on machine, which is virt-7.1 or ealier than it. It
means the optimization is enabled by default from virt-7.2. Besides,
'compact-highmem' property is added so that the optimization can be
explicitly enabled or disabled on all machine types by users.

4a4ff9edc6 hw/arm/virt: Improve high memory region address assignment
There are three high memory regions, which are VIRT_HIGH_REDIST2,
VIRT_HIGH_PCIE_ECAM and VIRT_HIGH_PCIE_MMIO. Their base addresses
are floating on highest RAM address. However, they can be disabled
in several cases.

(1) One specific high memory region is likely to be disabled by
    code by toggling vms->highmem_{redists, ecam, mmio}.

(2) VIRT_HIGH_PCIE_ECAM region is disabled on machine, which is
    'virt-2.12' or ealier than it.

(3) VIRT_HIGH_PCIE_ECAM region is disabled when firmware is loaded
    on 32-bits system.

(4) One specific high memory region is disabled when it breaks the
    PA space limit.

The current implementation of virt_set_{memmap, high_memmap}() isn't
optimized because the high memory region's PA space is always reserved,
regardless of whatever the actual state in the corresponding
vms->highmem_{redists, ecam, mmio} flag. In the code, 'base' and
'vms->highest_gpa' are always increased for case (1), (2) and (3).
It's unnecessary since the assigned PA space for the disabled high
memory region won't be used afterwards.

Improve the address assignment for those three high memory region by
skipping the address assignment for one specific high memory region if
it has been disabled in case (1), (2) and (3). The memory layout may
be changed after the improvement is applied, which leads to potential
migration breakage. So 'vms->highmem_compact' is added to control if
the improvement should be applied. For now, 'vms->highmem_compact' is
set to false, meaning that we don't have memory layout change until it
becomes configurable through property 'compact-highmem' in next patch.

d7ef5e16a1 hw/arm/boot: Set SCR_EL3.HXEn when booting kernel
When we direct boot a kernel on a CPU which emulates EL3, we need to
set up the EL3 system registers as the Linux kernel documentation
specifies:
     https://www.kernel.org/doc/Documentation/arm64/booting.rst

For CPUs with FEAT_HCX support this includes:
    - SCR_EL3.HXEn (bit 38) must be initialised to 0b1.

but we forgot to do this when implementing FEAT_HCX, which would mean
that a guest trying to access the HCRX_EL2 register would crash.

2b39abb2d6 hw/arm/boot: Set SME and SVE EL3 vector lengths when booting kernel
When we direct boot a kernel on a CPU which emulates EL3, we need
to set up the EL3 system registers as the Linux kernel documentation
specifies:
 https://www.kernel.org/doc/Documentation/arm64/booting.rst

For SVE and SME this includes:
    - ZCR_EL3.LEN must be initialised to the same value for all CPUs the
      kernel is executed on.
    - SMCR_EL3.LEN must be initialised to the same value for all CPUs the
      kernel will execute on.

Although we are technically compliant with this, the "same value" we
currently use by default is the reset value of 0.  This will end up
forcing the guest kernel's SVE and SME vector length to be only the
smallest supported length.

Initialize the vector length fields to their maximum possible value,
which is 0xf. If the implementation doesn't actually support that
vector length then the effective vector length will be constrained
down to the maximum supported value at point of use.

This allows the guest to use all the vector lengths the emulated CPU
supports (by programming the _EL2 and _EL1 versions of these
registers.)

98aa4c839d arm: re-randomize rng-seed on reboot
When the system reboots, the rng-seed that the FDT has should be
re-randomized, so that the new boot gets a new seed. Since the FDT is in
the ROM region at this point, we add a hook right after the ROM has been
added, so that we have a pointer to that copy of the FDT.

7cd5d384bb hw/arm/virt: Fix devicetree warnings about the virtio-iommu node
The "PCI Bus Binding to: IEEE Std 1275-1994" defines the compatible
string for a PCIe bus or endpoint as "pci<vendorid>,<deviceid>" or
similar. Since the initial binding for PCI virtio-iommu didn't follow
this rule, it was modified to accept both strings and ensure backward
compatibility. Also, the unit-name for the node should be
"device,function".

Fix corresponding dt-validate and dtc warnings:

  pcie@10000000: virtio_iommu@16:compatible: ['virtio,pci-iommu'] does not contain items matching the given schema
  pcie@10000000: Unevaluated properties are not allowed (... 'virtio_iommu@16' were unexpected)
  From schema: linux/Documentation/devicetree/bindings/pci/host-generic-pci.yaml
  virtio_iommu@16: compatible: 'oneOf' conditional failed, one must be fixed:

6b2f3ac945 hw/arm/virt: Use "msi-map" devicetree property for PCI
The "msi-parent" property can be used on the PCI node when MSIs do not
contain sideband data (device IDs) [1]. In QEMU, MSI transactions
contain the requester ID, so the PCI node should use the "msi-map"
property instead of "msi-parent". In our case the property describes an
identity map between requester ID and sideband data.

This fixes a warning when passing the DTB generated by QEMU to dtc,
following a recent change to the GICv3 node:

5f1d731c08 hw/arm/virt: Fix devicetree warning about the root node
The devicetree specification requires a 'model' property in the root
node. Fix the corresponding dt-validate warning:

  /: 'model' is a required property
  From schema: dtschema/schemas/root-node.yaml

Use the same name for model as for compatible. The specification
recommends that 'compatible' follows the format 'manufacturer,model' and
'model' follows the format 'manufacturer,model-number'. Since our
'compatible' doesn't observe this, 'model' doesn't really need to
either.

761c532ab1 target/arm: Make boards pass base address to armv7m_load_kernel()
Currently armv7m_load_kernel() takes the size of the block of memory
where it should load the initial guest image, but assumes that it
should always load it at address 0.  This happens to be true of all
our M-profile boards at the moment, but it isn't guaranteed to always
be so: M-profile CPUs can be configured (via init-svtor and
init-nsvtor, which match equivalent hardware configuration signals)
to have the initial vector table at any address, not just zero.  (For
instance the Teeny board has the boot ROM at address 0x0200_0000.)

Add a base address argument to armv7m_load_kernel(), so that
callers now pass in both base address and size. All the current
callers pass 0, so this is not a behaviour change.

f92bd43480 target/arm: Remove useless TARGET_BIG_ENDIAN check in armv7m_load_kernel()
Arm system emulation targets always have TARGET_BIG_ENDIAN clear, so
there is no need to have handling in armv7m_load_kernel() for the
case when it is defined.  Remove the unnecessary code.

Side notes:
 * our M-profile implementation is always little-endian (that is, it
   makes the IMPDEF choice that the read-only AIRCR.ENDIANNESS is 0)
 * if we did want to handle big-endian ELF files here we should do it
   the way that hw/arm/boot.c:arm_load_elf() does, by looking at the
   ELF header to see what endianness the file itself is

e1f045780b hw/arm/virt-acpi-build: Present the GICR structure properly for GICv4
With the introduction of the new TCG GICv4, build_madt() is badly broken
as we do not present any GIC Redistributor structure in MADT for GICv4
guests, so that they have no idea about where the Redistributor
register frames are. This fixes a Linux guest crash at boot time with
ACPI enabled and '-machine gic-version=4'.

While at it, let's convert the remaining hard coded gic_version into
enumeration VIRT_GIC_VERSION_2 for consistency.

398c01da9c aspeed/fby35: Fix owner of the BMC RAM memory region
A MachineState object is used as a owner of the RAM region and this
asserts in memory_region_init_ram() when QEMU is built with
CONFIG_QOM_CAST_DEBUG :

    /* This will assert if owner is neither NULL nor a DeviceState.
     * We only want the owner here for the purposes of defining a
     * unique name for migration. TODO: Ideally we should implement
     * a naming scheme for Objects which are not DeviceStates, in
     * which case we can relax this restriction.
     */
    owner_dev = DEVICE(owner);

Use the BMC and BIC objects as the owners of their memory regions.

004c8a8bc5 Align Raspberry Pi DMA interrupts with Linux DTS
There is nothing in the specs on DMA engine interrupt lines: it should have
been in the "BCM2835 ARM Peripherals" datasheet but the appropriate
"ARM peripherals interrupt table" (p.113) is nearly empty.

All Raspberry Pi models 1-3 (based on bcm2835) have
Linux device tree (arch/arm/boot/dts/bcm2835-common.dtsi +25):

    /* dma channel 11-14 share one irq */

This information is repeated in the driver code
(drivers/dma/bcm2835-dma.c +1344):

    /*
     * in case of channel >= 11
     * use the 11th interrupt and that is shared
     */

In this patch channels 0--10 and 11--14 are handled separately.

The BMC boots from the first flash device by fetching instructions
from the flash contents. Add an alias region on 0x0 for this
purpose. There are currently performance issues with this method (TBs
being flushed too often), so as a faster alternative, install the
flash contents as a ROM in the BMC memory space.
