2017-04-25AMD Geode: Move conflicting mainboard_romstage_entry()Marc Jones
The silicon specific mainboard_romstage_entry() in amd/cpu/car.h, which is used by all AMD silicon car code, caused a conflict. Move the silicon specific defines to silicon header files. Also, no longer include car.h in the romstage file.

Calling disable_cache_as_ram() with valuables in stack is not a stable solution, as per documentation AMD_DISABLE_STACK should destroy stack in cache.

2014-11-20AMD: Isolate AGESA and PI build environmentsKyösti Mälkki
To backport features introduced with recent Chromebooks and/or Intel boards in general, heavy work on the AMD AGESA platform infrastructure is required. With the AGESA PI available in binary form only, community members have little means to verify, debug and develop for the said platforms. Thus it makes sense to fork the existing agesawrapper interfaces, to give AMD PI platforms a clean and independent sandbox. New directory layout reflects the separation already taken place under 3rdparty/ and vendorcode/.

2014-11-14AMD (K8/fam10): Rewrite CAR migration in post_cache_as_ramKyösti Mälkki
Old routine copied all of CAR region as-is right below CONFIG_RAMTOP. Most of this region was reserved to interleave AP CPU address spaces and unused on BSP CPU. The only part of CAR region requiring a copy in RAM is the sysinfo structure. Improved routine changes this as follows: A region of size 'backup_size' below CONFIG_RAMTOP is cleared. In case of S3 resume, OS context from this region is first copied to high memory (CBMEM_ID_RESUME). At stack switch, CAR stack is discarded. Top of the stack for BSP is located at 'CONFIG_RAMTOP - car_size' for the remaining part of the romstage. This region is part of 'backup_size' and was zeroed before the switch took place. Before CAR is torn down the region of CAR_GLOBALS (and CAR_CBMEM), including the relevant sysinfo data for AP nodes memory training, is copied at 'CONFIG_RAMTOP - car_size'. NOTE: While CAR_GLOBAL variables are recovered, there are currently no means to calculate their offsets in RAM. NOTE: Boards with multiple CPU packages are likely already broken since bbc880ee amdk8/amdfam10: Use CAR_GLOBAL for sysinfo This moved the copy of sysinfo in RAM from above the stack to below the stack, but code for AP CPU's was not adjusted accordingly.
