2019-08-16amd/stoneyridge: Rename ramtop.c to memmap.cKyösti Mälkki

2019-08-15cpu/x86/smm: Define single smm_subregion()Kyösti Mälkki
At the moment we only have two splitting of TSEG, one with and one without IED. They can all use same implementation. Make configuration problems of TSEG region assertion failures. Rename file from stage_cache.c to tseg_region.c to reflect it's purpose.

2019-05-16soc/amd/common: Create AcpiMmio functionality from stoneyridgeMarshall Dawson
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.
