2021-02-01soc/amd/common: Drop ACPIMMIO GPIO bank separationKyösti Mälkki
It's assumed in ASL already that the banks appear one after other in ACPIMMIO space. There is no need for the separation of accessor functions by name.

Base address symbols for ACPIMMIO banks that would not get assigned at runtime must not resolve at linker-stage either.

2020-06-25Revert "soc/amd/common/block/acpimmio: Update acpimmio for psp_verstage"Kyösti Mälkki
This reverts commit 4883252912665f56c8e7801fe03a26594a1e9d5d. Almost everything in <amdblocks/acpimmio_map.h> is invalid for PSP as it does not have the same view of memory space. The prototypes xx_set/get_bar() are only valid for PSP as x86 cores will use the constant mapping defined in <amdblocks/acpimmio_map.h> The selected MMIO base address model depends of the architecture the stage is built for and, to current knowledge, nothing else. So the guards should have been with ENV_X86 vs ENV_ARM and not about CONFIG(VERSTAGE_BEFORE_BOOTBLOCK). For the ENV_ARM stage builds, <arch/io.h> file referenced in the previously added mmio_util_psp.c file has not been added to the tree. So there was some out-of-order submitting, which did not get caught as the build-testing of mixed-arch stages has not been incorporated into the tree yet. The previously added file mmio_util_psp.c is also 90% redundant with mmio_util.c.

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.
