This patch moves the ssram area in ve820 tab, and reunites the hpa1_low_part1/2 areas. The ve820 building code is refined. before: |<---low_1M--->| |<---hpa1_low_part1--->| |<---SSRAM--->| |<---hpa1_low_part2--->| |<---GPU_OpRegion--->| |<---ACPI DATA--->| |<---ACPI NVS--->| ---2G--- after: |<---low_1M--->| |<---hpa_low--->| |<---SSRAM--->| |<---GPU_OpRegion--->| |<---ACPI DATA--->| |<---ACPI NVS--->| ---2G--- The SSRAM area's address is described in the ACPI's RTCT/PTCT table. To simplify the SSRAM implementation, SSRAM area was identical mapped to GPA, and resulted in the divition of hpa_low. Then the ve820 building logic became too complicated. Now we managed to edit the guest's RTCT/PTCT table by offline tools in the former patch, so we can move the guest's SSRAM area, and reunite the hpa_low areas again. After doing this, this patch rewrites the ve820 building code in a much simpler way.
