Added 32 bits property for ASPEED GPIO. Previously it can only be
access in bitwise manner.
The changes to qobject is to index gpios with array indices on top of
accessing with registers. This allows for easier gpio access,
especially in tests with complex behaviors that requires large number
of gpios at a time, like fault injection and networking behaviors.
Indexing multiple gpios at once allows qmp/side band client to no
longer hardcode and populate register names and manipulate them
faster.

This patch introduces a dedicated ca35_boot_rom memory region and
copies the FMC0 flash data into it.
The motivation is to support the upcoming vbootrom. The vbootrom
replaces the existing BOOTMCU (RISC-V 32 SPL) flow, which currently reads
the "image-bmc" from FMC_CS0 and loads the following components
into DRAM:
- Trusted Firmware-A
- OP-TEE OS
- u-boot-nodtb.bin
- u-boot.dtb
After loading, BOOTMCU releases the CA35 reset so that CA35 can start
executing Trusted Firmware-A.
The vbootrom follows the same sequence: CA35 fetches "image-bmc" from FMC0
flash at the SPI boot ROM base address (0x100000000), parses the FIT image,
loads each component into its designated DRAM location, and then jumps to
Trusted Firmware-A.

In the original model, each subsystem (PSP, SSP, and TSP) created its own
set of 13 UART devices, resulting in a total of 39 UART instances. However,
on real AST2700 hardware, there is only one set of 13 UARTs shared among
all processors.
This commit reworks the UART handling to correctly model the shared
hardware design. The PSP now creates the full set of 13 UART instances,
while the SSP and TSP link to the corresponding shared UART device
through object properties.
Changes include:
- Add "DEFINE_PROP_LINK("uart", ...)" and "DEFINE_PROP_INT32("uart-dev", ...)"
to allow each coprocessor to reference a specific shared UART instance.
- Modify SSP to link to PSP’s UART4, and TSP to link to PSP’s UART7.
- Introduce "uart_alias" to remap the UART’s MMIO region into the coprocessor’s
memory space.
- Redirect the UART interrupt to the coprocessor’s NVIC, replacing the
default routing to the PSP’s GIC.
With this change, only one set of 13 UART devices is instantiated by the PSP,
while the SSP and TSP reuse them via aliasing and shared interrupt routing,
matching the real AST2700 hardware behavior.

AST2700 has a single SCU hardware block, memory-mapped at
0x12C02000–0x12C03FFF from the perspective of the main CA35 processor (PSP).
The SSP and TSP coprocessors access this same SCU block at different
addresses: 0x72C02000–0x72C03FFF.
Previously, each subsystem (PSP, SSP, and TSP) instantiated its own SCU
device, resulting in three independent SCU instances in the QEMU model.
In real hardware, however, only a single SCU exists and is shared among
all processors.
This commit reworks the SCU model to correctly reflect the hardware
behavior by allowing SSP and TSP to reference the PSP’s SCU instance.
The following changes are introduced:
- Add a scu property to AspeedCoprocessorState for linking the
coprocessor to the PSP’s SCU instance.
- Replace per-coprocessor SCU instantiation with a shared SCU link.
- Add "MemoryRegion scu_alias" to model address remapping for SSP and TSP.
- Create SCU alias regions in both SSP and TSP coprocessors and map
them at 0x72C02000 to mirror the PSP’s SCU registers.
- Ensure the SCU device in PSP is realized before SSP/TSP alias setup.
With this change, PSP, SSP, and TSP now share a consistent SCU state,
matching the single-SCU hardware design of AST2700.

AST2700 has a 128KB SRAM, physically mapped at 0x10000000–0x1001FFFF for
the PSP (CA35) processor. The TSP coprocessor shares this same SRAM but
accesses it through a different address window at 0x70000000–0x7001FFFF.
To model this shared-memory behavior in QEMU, this commit introduces a
linked SRAM property and alias mapping between the PSP and TSP subsystems.
Changes include:
- Add the SRAM alias mapping at 0x70000000 in aspeed_ast27x0-tsp.c.
- In aspeed_ast27x0-fc.c, connect the TSP coprocessor’s "sram" link to
the PSP’s SRAM region.
- Ensure the alias region is initialized during TSP SoC realization so
the TSP can correctly access shared SRAM through its own address space.
This ensures that the TSP and PSP share the same physical SRAM backing.

Uploading the cache from the runner takes a long time in the MSYS2
job, mostly due to the size of the compiler cache.
However, looking at runs with a non-poluted cache, it seems like
you can get a build with a 99% hit rate already with ~ 160 MiB cache
size, so the compiler cache with 500 MiB certainly contains a lot of
stale files. Thus decrease the size of the ccache to a more reasonable
value to speed up the MSYS2 job in our CI.
While at it, also add a "du -sh" for the build folder to get a better
feeling for the amount of object code that is required for the build,
and publish the list of files in /var/cache to be able to better
analyze what is really clogging our cache here.

Enhance uftrace_symbols.py to generate .dbg files, containing
source location for every symbol present in .sym file.
It allows to use `uftrace {replay,dump} --srcline` and show origin of
functions, connecting trace to original source code.
It was first implemented with pyelftools DWARF parser, which was way
too slow (~minutes) to get locations for every symbol in the linux
kernel. Thus, we use `addr2line` instead, which runs in seconds.
As well, there were some bugs with latest pyelftools release,
requiring to run master version, which is not installable with pip.
Thus, since we now require binutils (addr2line), we can ditch pyelftools
based implementation and simply rely on `nm` to get symbols information,
which is faster and better.

and then calling stat() to check that the values read back correctly.
Unfortunately this is flaky, as it will fail if some other process

In theory we could defend against this by e.g. operating on files in

this isn't worth the hassle. Just drop the check on atime.

While working out what hoops to jump through to get a full set of
aarch32 packages installed on the aarch64 runner it was pointed out 32
bit host support is deprecated. As the extra packages where needed for
system emulation (marked deprecated since 8.0!) there didn't seem much
point keeping this in.
While the full expunging of 32 bit host support will probably be done
for 11.0 we can at least reduce the CI burden a bit now.

Most of the test is pure boilerplate so to save ourselves from
repetition move all the main bits into a minimal copy of
native_build_job_template but without the caching.
We keep all the current allow_fail and configure setups but do take
the opportunity to replace the -j`nproc --ignore=40` hack with
something that almost, but not quite, saturates the machine its being
built on.

The coverity-scan upload job has started failing as of 30th
September:
[ERROR] Cannot find '/usr/bin/file' command, and no 'file' command is found in the PATH
Coverity Capture uses this tool to identify the file type of executables.
Please ensure '/usr/bin/file' is available, or add the 'file' utility to your PATH.
This seems to have broken when we moved our containers from Fedora 40
to 41 -- probably F40 indirectly pulled in 'file' via some other
dependency, but in F41 it does not.
Explicitly install 'file' for the coverity job, in the same way we
already do for curl and wget.

The purpose of the prepare script is to invoke `cpp` to preprocess input
to idef-parser by expanding a few select macros. On macOS `cpp`
expands into `clang ... -traditional-cpp` which breaks macro
concatenation. Replace `cpp` with `${compiler} -E`
and replace the script with a meson custom_target.

In order to correspond with the kernel, we've now (1) moved the
preds[] to the right offset and combined the representation as a single
ulong "p3_0", (2), added the cs{0,1} registers, (3) added a pad for 48
words, (4) added the user regs structure to an 8-byte aligned
target_sigcontext structure.
