From c357fd6a1f79e2d7b0a1bd01994b8d33925bfff5 Mon Sep 17 00:00:00 2001 From: Olivier Martin Date: Fri, 10 Jan 2014 11:27:31 +0000 Subject: ArmPkg/ArmPkg.dec: Redefined PcdSystemMemory(Base|Size) as UINT64 The System Memory region might be out of the 32-bit memory space. This change has been validated on the FVP AArch64 model using 4GB of DRAM at 0x8_0000_0000: - # System Memory (2GB) - gArmTokenSpaceGuid.PcdSystemMemoryBase|0x80000000 - gArmTokenSpaceGuid.PcdSystemMemorySize|0x80000000 + # System Memory (4GB) + gArmTokenSpaceGuid.PcdSystemMemoryBase|0x800000000 + gArmTokenSpaceGuid.PcdSystemMemorySize|0x100000000 EFI Shell and Linux kernel boot successfully. Note: This change has not been validated on AArch32. I expect some early assembly code to not work.
