cdafeda357 9pfs: fix 'total_open_fd' decrementation
According to 'man 2 close' errors returned by close() should only be used
for either diagnostic purposes or for catching data loss due to a previous
write error, as an error result of close() usually indicates a deferred
error of a previous write operation.

Therefore not decrementing 'total_open_fd' on a close() error is wrong
and would yield in a higher open file descriptor count than actually the
case, leading to 9p server reclaiming open file descriptors too soon.

v9fs_getattr() currently peeks into V9fsFidOpenState to know if a fid
has a valid file descriptor or directory stream. Even though the fields
are accessible, this is an implementation detail of the local backend
that should not be manipulated directly by the server code.

89f7b4da76 9pfs: fix FD leak and reduce latency of v9fs_reclaim_fd()
This patch fixes two different bugs in v9fs_reclaim_fd():

1. Reduce latency:

This function calls v9fs_co_close() and v9fs_co_closedir() in a loop. Each
one of the calls adds two thread hops (between main thread and a fs driver
background thread). Each thread hop adds latency, which sums up in
function's loop to a significant duration.

Reduce overall latency by open coding what v9fs_co_close() and
v9fs_co_closedir() do, executing those and the loop itself altogether in
only one background thread block, hence reducing the total amount of
thread hops to only two.

2. Fix file descriptor leak:

The existing code called v9fs_co_close() and v9fs_co_closedir() to close
file descriptors. Both functions check right at the beginning if the 9p
request was cancelled:

    if (v9fs_request_cancelled(pdu)) {
        return -EINTR;
    }

So if client sent a 'Tflush' message, v9fs_co_close() / v9fs_co_closedir()
returned without having closed the file descriptor and v9fs_reclaim_fd()
subsequently freed the FID without its file descriptor being closed, hence
leaking those file descriptors.

This 2nd bug is fixed by this patch as well by open coding v9fs_co_close()
and v9fs_co_closedir() inside of v9fs_reclaim_fd() and not performing the
v9fs_request_cancelled(pdu) check there.

61da38db70 9pfs: fix concurrent v9fs_reclaim_fd() calls
Even though this function is serialized to be always called from main
thread, v9fs_reclaim_fd() is dispatching the coroutine to a worker thread
in between via its v9fs_co_*() calls, hence leading to the situation where
v9fs_reclaim_fd() is effectively executed multiple times simultaniously,
which renders its LRU algorithm useless and causes high latency.

Fix this by adding a simple boolean variable to ensure this function is
only called once at a time. No synchronization needed for this boolean
variable as this function is only entered and returned on main thread.

a74faf35ef hw/arm: Introduce ASPEED AST2700 A1 full core machine
- Added new machine type `ast2700fc` with full core support.
- Defined `Ast2700FCState` structure for the new machine type.
- Implemented initialization functions for CA35, SSP, and TSP components.
- Updated `ast2700fc_types` to include the new machine type.
- Set machine class properties for `ast2700fc`.

Test Step:
- Download ast2700-default-obmc.tar.gz from AspeedTech-BMC OpenBmc
  release page.
- Run the following QEMU command:

  ```
  IMGDIR=~/path/to/image
  UBOOT_SIZE=$(stat --format=%s -L ${IMGDIR}/u-boot-nodtb.bin)

  ./qemu-system-aarch64 -machine ast2700fc \
  -device loader,force-raw=on,addr=0x400000000,file=${IMGDIR}/u-boot-nodtb.bin \
  -device loader,force-raw=on,addr=$((0x400000000 + ${UBOOT_SIZE})),file=${IMGDIR}/u-boot.dtb \

- After starting QEMU, serial devices will be redirected:

  char device redirected to /dev/pts/51 (label serial0)
  char device redirected to /dev/pts/52 (label serial1)
  char device redirected to /dev/pts/53 (label serial2)

- serial0 is the console for the four Cortex-A35 primary processors,
  serial1 and serial2 are the consoles for the two Cortex-M4 coprocessors.

- Connect to the consoles using a terminal emulator.

2d64e6a009 hw/arm/aspeed_ast27x0-tsp: Introduce AST27x0 A1 TSP SoC
AST2700 TSP(Tertiary Service Processor) is a Cortex-M4 coprocessor
The patch adds support for TSP with following update:

- Introduce Aspeed27x0TSPSoCState structure in aspeed_soc.h
- Implement initialization and realization functions
- Add support for UART, INTC, and SCU devices
- Map unimplemented devices for IPC and SCUIO
- Defined memory map and IRQ maps for AST27x0 A1 TSP SoC

The IRQ mapping is similar to AST2700 CA35 SoC, featuring a two-level
interrupt controller.

Difference from AST2700:

    - AST2700
      - Support GICINT128 to GICINT136 in INTC
      - The INTCIO GIC_192_201 has 10 output pins, mapped as follows:
          Bit 0 -> GIC 192
          Bit 1 -> GIC 193
          Bit 2 -> GIC 194
          Bit 3 -> GIC 195
          Bit 4 -> GIC 196

    - AST2700-tsp
      - Support TSPINT128 to TSPINT136 in INTC
      - The INTCIO TSPINT_160_169 has 10 output pins, mapped as follows:

Maps following unimplemented devices in SoC memory
- dpmcu
- iomem
- iomem0
- iomem1
- ltpi

Iomem, Iomem0 and Iomem1 include unimplemented controllers in the memory ranges 0x0 - 0x1000000, 0x120000000 - 0x121000000 and
0x14000000 - 0x141000000.

For instance:
- USB hub at 0x12010000
- eSPI at 0x14C5000
- PWM at 0x140C0000

DPMCU stands for Display Port MCU controller. LTPI is used to connect to AST1700.
AST1700 is an I/O expander that supports the DC-SCM 2.1 LTPI protocol.
It provides AST2700 with additional GPIO, UART, I3C, and other interfaces.

3d881164d4 qemu: Convert target_name() to TargetInfo API
Have target_name() be a target-agnostic method, dispatching
to a per-target TargetInfo singleton structure.
By default a stub singleton is used. No logical change
expected.

The QAPI-generated 'TargetInfo' structure name is only used

similarly named. Rename the QAPI one, since structure names

141af1b31b hw/net/can: Fix type conflict of GLib function pointers
On Emscripten, function pointer casts can result in runtime failures due to
strict function signature checks. This affects the use of g_list_sort and
g_slist_sort, which internally perform function pointer casts that are not
supported by Emscripten. To avoid these issues, g_list_sort_with_data and
g_slist_sort_with_data should be used instead, as they do not rely on
function pointer casting.

was depending on (TARGET_WORDS_BIGENDIAN). Later in commit
ee3eb3a7ce ("Replace TARGET_WORDS_BIGENDIAN") the definition was
renamed as TARGET_BIG_ENDIAN but we didn't update the helper.
