2017-08-16AGESA: Cleanup ACPI S3 supportKyösti Mälkki
Due to low-memory corruptions S3 support has now been (at least temporarily) removed from AGESA platfroms. Should we bring it back one day, CAR teardown on S3 path will happen with an empty stack so ugly backup/recovery of the stack will no longer be used. If S3 feature is brought back, resume path code for FCH will also see partial rewrite and agesawrapper.c file will not be part of that.

2017-08-02AGESA: Introduce AGESA_LEGACY_WRAPPER and its counterpartKyösti Mälkki
We define AGESA_LEGACY_WRAPPER a method of calling AGESA via functions in agesawrapper.c file. The approach implemented there makes it very inconvenient to do board-specific customisation or present common platform-specific features. Seems like it also causes assertion errors on AGESA side. The flag is applied here to all boards and then individually removed one at a time, as things get tested. New method is not to call AGESA internal functions directly, but via the dispatcher. AGESA call parameters are routed to hooks in both platform and board -directories, to allow for easy capture or modification as needed. For each AGESA dispatcher call made, eventlog entries are replayed to the console log. Also relocations of AGESA heap that took place are recorded. New method is expected to be compatible with binaryPI.
