[PATCH v2 0/9] hw/arm/aspeed: Introduce initial AST1040 support

[Jamin Lin <jamin_lin@aspeedtech.com>]

This series introduces the initial ASPEED AST1040 support for QEMU.

AST1040 is the next-generation bridge/BIC controller platform
following AST1030 and is based on an ARM Cortex-M4F CPU core.
Since QEMU currently does not provide Cortex-M4F support, the
existing Cortex-M4 CPU model is used temporarily.

The current implementation provides enough functionality to boot
basic firmware environments with UART console support, HyperRAM/SRAM
mapping, and NVIC interrupt handling.

Currently this series is able to boot Zephyr successfully to the
shell prompt:

  uart:~$

Example command line:

  ./build/qemu-system-arm \
      -machine ast1040-evb \
      -kernel <zephyr.elf> \
      -serial mon:stdio \
      -snapshot \
      -nographic

There are many different types of RAM, including DRAM, SRAM, SDRAM, PSRAM,
SECSRAM, and HyperRAM. To support these memory types, we need to introduce
distinct variable names for their memory regions and memory sizes.

In addition, the SoC contains multiple SRAM instances. To make the code more
flexible and maintainable, I am considering changing the array structure to
support internal memory types such as SRAM, SDRAM, PSRAM, HyperRAM, and SECSRAM.

For example:

sram[NUM]
sram_size[NUM]
ASPEED_DEV_SRAMX

v1:
  - AST1040 silicon revision ID
  - SDRAM support in the Aspeed SoC framework
  - Initial AST1040 SoC model
  - AST1040 EVB machine model

v2: 
  - Add AST1040 functional test
  - Add AST1040 documentation
  - Convert SRAM MemoryRegion to array type
  - Convert SRAM size definition to array type
