Change subject: binaryPI: implement C bootblock
......................................................................

Patch Set 8:

This patchset works with apu2 C bootblock change. However still can not move to SOC_AMD_COMMON_BLOCK_CAR, thus added implementation to drivers/amd/agesa/cahce_as_ram.S .

Problems with SOC_AMD_COMMON_BLOCK_CAR:
- either frozen at postcode A2
- or reset loop in AmdInitReset

Possible reasons:
- FPU and SSE initialization missing in SOC_AMD_COMMON_BLOCK_CAR path
- BSP stack setup to _ecar_stack missing in SOC_AMD_COMMON_BLOCK_CAR
