2017-08-02binaryPI: Introduce BINARYPI_LEGACY_WRAPPER and its counterpartKyösti Mälkki
We define BINARYPI_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.

2017-08-02AGESA: Add romstage timestampsKyösti Mälkki
Experiments on f14 f15tn and 16kb suggest that TSC counter value shifts at end of raminit. To account for this all previously stored values in timestamp table are also divided by 4.

2017-08-02AGESA: Implement EARLY_CBMEM_INITKyösti Mälkki
Boards without AGESA_LEGACY_WRAPPER gain EARLY_CBMEM_INIT. This does not apply to family12 and family14 just yet, as they do invalidate without write-back on CAR teardown.

2017-08-02AGESA: Move romstage-ramstage splitlineKyösti Mälkki
In AGESA specification AmdInitEnv() is to be called once host memory allocator has started. In coreboot context this could mean either availability of CBMEM or malloc heap. As for AmdS3LateRestore(), there is no requirement to have it run as part of the romstage either.

2017-04-05AGESA: Disable CAR with empty stackKyösti Mälkki
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.
