From 964680c124d0826c8e08b4c59cc4193e9a912ea1 Mon Sep 17 00:00:00 2001 From: oliviermartin Date: Thu, 31 Mar 2011 12:21:41 +0000 Subject: ArmPlatformPkg/ArmPlatformLib: Move the UEFI memory partionning to MemoryInitPei Formerly, each platform was responsible to declare the location of its UEFI memory region (used by PEI and DXE Foundations). The ArmPlatformLib was also declaring every region of its partitionned system memory with a System Resource HOB. In this new model, the MemoryInit expects the system memory to be declared with the PCDs gArmTokenSpaceGuid.PcdSystemMemoryBase/Size. These PCDs declare the largest continuous DRAM region. Additional regions can be declared with the ArmPLatformLib function ArmPlatformGetAdditionalSystemMemory(). Now, it is the PEIM that partitions the system memory for every platform. It installs a region of the size PcdSystemMemoryUefiRegionSize (default 128MB) for the PEI permanent memory at the top of the DRAM region. And a region of gArmPlatformTokenSpaceGuid.PcdSystemMemoryFixRegionSize (default 128MB) is declared at the base of the system memory. This region is used for the allocation that requires fixed address or have some constraints on their locations. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@11481 6f19259b-4bc3-4df7-8a09-765794883524 --- ArmPlatformPkg/Include/Library/ArmPlatformLib.h | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) (limited to 'ArmPlatformPkg/Include') diff --git a/ArmPlatformPkg/Include/Library/ArmPlatformLib.h b/ArmPlatformPkg/Include/Library/ArmPlatformLib.h index 83c19baabd..ec95941b51 100644 --- a/ArmPlatformPkg/Include/Library/ArmPlatformLib.h +++ b/ArmPlatformPkg/Include/Library/ArmPlatformLib.h @@ -170,8 +170,9 @@ VOID ArmPlatformGetVirtualMemoryMap ( EFI Memory region.
