soc/amd/common: Create AcpiMmio functionality from stoneyridge Move the stoneyridge AcpiMmio code into soc/amd/common. The SB800 southbridge introduced the MMIO hardware blocks at 0xfed80000 commonly known as AcpiMmio. Implementations beginning with Mullins enable decode in PMx04. Older designs use PMx24 and allow for configuring the base address. Future work may support the older version. Comparing the documentation for AMD's RRGs and BKDGs, it is evident that the block locations have not been reassigned across products. In some cases, address locations are deprecated and new ones consumed, e.g. the early GPIO blocks were simpler at offset 0x100 and the newer GPIO banks are now at 0x1500, 0x1600, and 0x1700. Note: Do not infer the definitions within the hardware blocks are consistent across family/model products.

soc/amd: Implement common reset API Add an `amdblocks` internal API and rename soft_reset() => warm_reset() hard_reset() => cold_reset() as these terms are commonly used in the surrounding code. On Stoney Ridge, make board_reset() call cold_reset() to keep current behaviour of common code calling hard_reset(). But add a TODO if this is intended. Note: Stoney Ridge is using CF9 for the actual reset but the configuration for a cold reset doesn't use the usual full reset bit but some other mechanism.

amd/stoneyridge: Add warm reset detection Extend the existing reset handling features in Stoney Ridge to plan for, and recognize, warm resets. The ColdRstDet bit is always zero on a cold reset, and is intended as a mechanism for the BIOS to determine the type of a reset that occurred. Set ColdRstDet=1 after all cores have been initialized, so that any subsequent reset may be identified as warm/cold. A later patch will check the value during mp_init.
