2016-04-29ArmPlatformPkg/PrePi: allow unicore version to be used on MP hardwareArd Biesheuvel
When combining UEFI firmware built from Tianocore with ARM Trusted Firmware running in EL3, it is the responsibility of ATF that only a single core enters the UEFI firmware in EL2, and the remaining cores are released directly to the OS via PSCI SMC calls. In this case, we don't need the MpCore flavor of PrePi or PrePeiCore, but the UniCore flavor currently checks the CPU identification registers directly, and refuses to proceed if the boot CPU is part of a MpCore system. So drop the ASSERT()'s that implement this check.

2016-03-25ArmPlatformPkg: fixups for 64-bit pointersLeendert van Doorn
This retypes some stack base PCD as 64-bit, and fixes up a number of references to 64-bit PCDs (including the retypes ones), to use the correct PcdGet64() accessors. Note that, in the case of FixedPcdGet64, this does not actually caused any problems, since that resolves to an immediate value. But the generic PcdGetxx accessors should be typed according to the size of the PCD.

2016-02-02ArmPlatformPkg: Rectify file modesEvan Lloyd
Problems have been encountered because some of the source files have execute permission set. This can cause git to report them as changed when they are checked out onto a file system with inherited permissions. This has been seen using Cygwin, MinGW and PowerShell Git. This patch makes no change to source file content, and only aims to correct the file modes/permissions.

2015-11-27ArmPlatformPkg/PrePi: remove global variable allocation from lowlevel initArd Biesheuvel
Now that we dropped all ArmPlatformGlobalVariableLib dependencies, there is no longer a need to allocate and clear out the global variable region in the PrePi init code. So remove it.

2015-07-06ArmPlatformPkg/PrePi: Make dynamic the top of the System MemoryOlivier Martin
This change allows to change the top of the System Memory that was hardcoded by: FixedPcdGet64 (PcdSystemMemoryBase) + FixedPcdGet64 (PcdSystemMemorySize) It allows to add support when the Trusted Firmware reserves the top of the System Memory as Trusted. The size of this region might not be known in advance. Note: The reason why the start of the System Memory has not been made dynamic is because the early code calculates where to place the stack from the top of the System Memory. So there is no need to make the start of the System Memory a dynamic value at the early stage of the boot phase.

2014-04-03ArmPlatformPkg/PrePi: Use the same calculation to declare the stack size as ↵Olivier Martin
in the entrypoint The stack size in the entrypoint (ie: $ARCH/ModuleEntryPoint.S) is calculated such as StackSize = PrimaryCoreStack + (core_count - 1) * SecondaryCoreStack While we were declaring the stacksize into the stack hob as: StackSize = PrimaryCoreStack + (cluster * 8) * SecondaryCoreStack If the number of cluster (ie: PcdClusterCount) were not defined correctly then the stack size declaration were not correct. It could cause stack corruption if the allocator allocates memory in this range.

These PCDs by default use the ClusterId and CoreId to identify the core. And the primary core is defined as the ClusetrId=0 and CoreId=0.

2011-07-06ArmPlatformPkg: Change the memory model for the ARM Platform componentsoliviermartin
In the former memory model, the UEFI firmware was expected to be located at the top of the system memory. Stacks & Pi memory regions were set below the firmware. On some platform, the UEFI firmware could be shadowed by the ROM firmware (case of the BeagleBoard) and in some cases the firmware is copied at the beginning of the system memory. With this new memory model, stack and Pi/DXE memory regions are set at the top of the system memory wherever the UEFI firmware is located in the memory map. Because DXE core does not support shadowed firmwares, the system memory covered by the UEFI firmware is marked as 'Non Present' to avoid to be overlapped by DXE allocations. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@11992 6f19259b-4bc3-4df7-8a09-765794883524
