The ve820 table' hpa1_low area is divided into two parts, which is making the code too complicated and causing problems. Moving the entries that divides the hpa1_low could make things easier. This patch moves the GPU OpRegion to the tail area of 2G, consecutive to the acpi data/nvs area. before: |<---low_1M--->| |<---hpa1_low_part1--->| |<---SSRAM--->| |<---GPU_OpRegion--->| |<---hpa1_low_part2--->| |<---ACPI DATA--->| |<---ACPI NVS--->| ---2G--- after: |<---low_1M--->| |<---hpa1_low_part1--->| |<---SSRAM--->| |<---hpa1_low_part2--->| |<---GPU_OpRegion--->| |<---ACPI DATA--->| |<---ACPI NVS--->| ---2G--- Tracked-On: #6674 Signed-off-by: Zhou, Wu <wu.zhou@intel.com> Reviewed-by: Victor Sun <victor.sun@intel.com> Reviewed-by: Wang, Yu1 <yu1.wang@intel.com>
