a71e264614 hw/arm/mps3r: Add UARTs
This board has a lot of UARTs: there is one UART per CPU in the
per-CPU peripheral part of the address map, whose interrupts are
connected as per-CPU interrupt lines.  Then there are 4 UARTs in the
normal part of the peripheral space, whose interrupts are shared
peripheral interrupts.

Connect and wire them all up; this involves some OR gates where
multiple overflow interrupts are wired into one GIC input.

273a70ae82 hw/arm/mps3r: Initial skeleton for mps3-an536 board
The AN536 is another FPGA image for the MPS3 development board. Unlike
the existing FPGA images we already model, this board uses a Cortex-R
family CPU, and it does not use any equivalent to the M-profile
"Subsystem for Embedded" SoC-equivalent that we model in hw/arm/armsse.c.
It's therefore more convenient for us to model it as a completely
separate C file.

This commit adds the basic skeleton of the board model, and the
code to create all the RAM and ROM. We assume that we're probably
going to want to add more images in future, so use the same
base class/subclass setup that mps2-tz.c uses, even though at
the moment there's only a single subclass.

Following commits will add the CPUs and the peripherals.

2a5ee4e18d hw/misc/mps2-scc: Make changes needed for AN536 FPGA image
The MPS2 SCC device is broadly the same for all FPGA images, but has
minor differences in the behaviour of the CFG registers depending on
the image. In many cases we don't really care about the functionality
controlled by these registers and a reads-as-written or similar
behaviour is sufficient for the moment.

For the AN536 the required behaviour is:

 * A_CFG0 has CPU reset and halt bits
    - implement as reads-as-written for the moment
 * A_CFG1 has flash or ATCM address 0 remap handling
    - QEMU doesn't model this; implement as reads-as-written
 * A_CFG2 has QSPI select (like AN524)
    - implemented (no behaviour, as with AN524)
 * A_CFG3 is MCC_MSB_ADDR "additional MCC addressing bits"
    - QEMU doesn't care about these, so use the existing
      RAZ behaviour for convenience
 * A_CFG4 is board rev (like all other images)
    - no change needed
 * A_CFG5 is ACLK frq in hz (like AN524)
    - implemented as reads-as-written, as for other boards
 * A_CFG6 is core 0 vector table base address
    - implemented as reads-as-written for the moment
 * A_CFG7 is core 1 vector table base address
    - implemented as reads-as-written for the moment

Make the changes necessary for this; leave TODO comments where
appropriate to indicate where we might want to come back and
implement things like CPU reset.

The other aspects of the device specific to this FPGA image (like the
values of the board ID and similar registers) will be set via the
device's qdev properties.

5f3bbbdbd0 hw/misc/mps2-scc: Factor out which-board conditionals
The MPS SCC device has a lot of different flavours for the various
different MPS FPGA images, which look mostly similar but have
differences in how particular registers are handled.  Currently we
deal with this with a lot of open-coded checks on scc_partno(), but
as we add more board types this is getting a bit hard to read.

Factor out the conditions into some functions which we can
give more descriptive names to.

f2b4a98930 target/arm: Allow access to SPSR_hyp from hyp mode
Architecturally, the AArch32 MSR/MRS to/from banked register
instructions are UNPREDICTABLE for attempts to access a banked
register that the guest could access in a more direct way (e.g.
using this insn to access r8_fiq when already in FIQ mode).  QEMU has
chosen to UNDEF on all of these.

However, for the case of accessing SPSR_hyp from hyp mode, it turns
out that real hardware permits this, with the same effect as if the
guest had directly written to SPSR. Further, there is some
guest code out there that assumes it can do this, because it
happens to work on hardware: an example Cortex-R52 startup code
fragment uses this, and it got copied into various other places,
including Zephyr. Zephyr was fixed to not use this:
 https://github.com/zephyrproject-rtos/zephyr/issues/47330
but other examples are still out there, like the selftest
binary for the MPS3-AN536.

For convenience of being able to run guest code, permit
this UNPREDICTABLE access instead of UNDEFing it.

b2f24983db target/arm: Use new CBAR encoding for all v8 CPUs, not all aarch64 CPUs
We support two different encodings for the AArch32 IMPDEF
CBAR register -- older cores like the Cortex A9, A7, A15
have this at 4, c15, c0, 0; newer cores like the
Cortex A35, A53, A57 and A72 have it at 1 c15 c0 0.

When we implemented this we picked which encoding to
use based on whether the CPU set ARM_FEATURE_AARCH64.
However this isn't right for three cases:
 * the qemu-system-arm 'max' CPU, which is supposed to be
   a variant on a Cortex-A57; it ought to use the same
   encoding the A57 does and which the AArch64 'max'
   exposes to AArch32 guest code
 * the Cortex-R52, which is AArch32-only but has the CBAR
   at the newer encoding (and where we incorrectly are
   not yet setting ARM_FEATURE_CBAR_RO anyway)
 * any possible future support for other v8 AArch32
   only CPUs, or for supporting "boot the CPU into
   AArch32 mode" on our existing cores like the A57 etc

Make the decision of the encoding be based on whether
the CPU implements the ARM_FEATURE_V8 flag instead.

This changes the behaviour only for the qemu-system-arm
'-cpu max'. We don't expect anybody to be relying on the
old behaviour because:
 * it's not what the real hardware Cortex-A57 does
   (and that's what our ID register claims we are)
 * we don't implement the memory-mapped GICv3 support
   which is the only thing that exists at the peripheral
   base address pointed to by the register

ac1d88e9e7 target/arm: Don't get MDCR_EL2 in pmu_counter_enabled() before checking ARM_FEATURE_PMU
It doesn't make sense to read the value of MDCR_EL2 on a non-A-profile

#6  0x00007ffff4b95e96 in __GI___assert_fail
    (assertion=0x5555565a8c70 "!arm_feature(env, ARM_FEATURE_M)", file=0x5555565a6e5c "../../target/arm/helper.c", line=12600, function=0x5555565a9560 <__PRETTY_FUNCTION__.0> "arm_security_space_below_el3") at ./assert/assert.c:101

#9  0x0000555555ea942f in arm_mdcr_el2_eff (env=0x555557bc8190) at ../../target/arm/internals.h:1512

We might call pmu_counter_enabled() on an M-profile CPU (for example
from the migration pre/post hooks in machine.c); this should always
return false because these CPUs don't set ARM_FEATURE_PMU.

Avoid the assertion by not calling arm_mdcr_el2_eff() before we
have done the early return for "PMU not present".

This fixes an assertion failure if you try to do a loadvm or
savevm for an M-profile board.

1ec896fe7c hw/arm/virt: Wire up non-secure EL2 virtual timer IRQ
Armv8.1+ CPUs have the Virtual Host Extension (VHE) which adds a
non-secure EL2 virtual timer.  We implemented the timer itself in the
CPU model, but never wired up its IRQ line to the GIC.

Wire up the IRQ line (this is always safe whether the CPU has the
interrupt or not, since it always creates the outbound IRQ line).
Report it to the guest via dtb and ACPI if the CPU has the feature.

The DTB binding is documented in the kernel's
Documentation/devicetree/bindings/timer/arm\,arch_timer.yaml
and the ACPI table entries are documented in the ACPI specification
version 6.3 or later.

Because the IRQ line ACPI binding is new in 6.3, we need to bump the
FADT table rev to show that we might be using 6.3 features.

Note that exposing this IRQ in the DTB will trigger a bug in EDK2
versions prior to edk2-stable202311, for users who use the virt board
with 'virtualization=on' to enable EL2 emulation and are booting an
EDK2 guest BIOS, if that EDK2 has assertions enabled.  The effect is
that EDK2 will assert on bootup:

 ASSERT [ArmTimerDxe] /home/kraxel/projects/qemu/roms/edk2/ArmVirtPkg/Library/ArmVirtTimerFdtClientLib/ArmVirtTimerFdtClientLib.c(72): PropSize == 36 || PropSize == 48

If you see that assertion you should do one of:
 * update your EDK2 binaries to edk2-stable202311 or newer
 * use the 'virt-8.2' versioned machine type
 * not use 'virtualization=on'

(The versions shipped with QEMU itself have the fix.)

We deliberately don't include qtests_npcm7xx in qtests_aarch64,
because we already get the coverage of those tests via qtests_arm,
and we don't want to use extra CI minutes testing them twice.

In commit 327b680877 we added it to qtests_aarch64; revert
that change.

f94d58f260 hw/pci-host/raven.c: Mark raven_io_ops as implementing unaligned accesses
The raven_io_ops MemoryRegionOps is the only one in the source tree
which sets .valid.unaligned to indicate that it should support
unaligned accesses and which does not also set .impl.unaligned to
indicate that its read and write functions can do the unaligned
handling themselves.  This is a problem, because at the moment the
core memory system does not implement the support for handling
unaligned accesses by doing a series of aligned accesses and
combining them (system/memory.c:access_with_adjusted_size() has a
TODO comment noting this).

Fortunately raven_io_read() and raven_io_write() will correctly deal
with the case of being passed an unaligned address, so we can fix the
missing unaligned access support by setting .impl.unaligned in the
MemoryRegionOps struct.

681dfc0d55 linux-user/aarch64: Choose SYNC as the preferred MTE mode
The API does not generate an error for setting ASYNC | SYNC; that merely
constrains the selection vs the per-cpu default.  For qemu linux-user,
choose SYNC as the default.

588a09dace virtio-gpu-rutabaga.c: override resource_destroy method
When the Rutabaga GPU device frees resources, it calls
rutabaga_resource_unref for that resource_id. However, when the generic
VirtIOGPU functions destroys resources, it only removes the
virtio_gpu_simple_resource from the device's VirtIOGPU->reslist list.
The rutabaga resource associated with that resource_id is then leaked.

This commit overrides the resource_destroy class method introduced in
the previous commit to fix this.

330399bd89 virtio-gpu.c: add resource_destroy class method
When destroying/unrefing resources, devices such as virtio-gpu-rutabaga
need to do their own bookkeeping (free rutabaga resources that are
associated with the virtio_gpu_simple_resource).

This commit adds a class method so that virtio-gpu-rutabaga can override
it in the next commit.

8b162082cb hw/display/virtio-gpu.c: use reset_bh class method
While the VirtioGPU type has a reset_bh field to specify a reset
callback, it's never used. virtio_gpu_reset() calls the general
virtio_gpu_reset_bh() function for all devices that inherit from
VirtioGPU.

While no devices override reset_bh at the moment, a device reset might
require special logic for implementations in the future.

8700ee15de hw/cxl: Standardize all references on CXL r3.1 and minor updates
Previously not all references mentioned any spec version at all.
Given r3.1 is the current specification available for evaluation at
www.computeexpresslink.org update references to refer to that.
Hopefully this won't become a never ending job.

A few structure definitions have been updated to add new fields.
Defaults of 0 and read only are valid choices for these new DVSEC
registers so go with that for now.

There are additional error codes and some of the 'questions' in
the comments are resolved now.

Update documentation reference to point to the CXL r3.1 specification
with naming closer to what is on the cover.

For cases where there are structure version numbers, add defines
so they can be found next to the register definitions.
