2012-09-28ArmPlatformPkg: Introduction of gArmPlatformTokenSpaceGuid.PcdCoreCountoliviermartin
On ARM PLatforms, there is no standard way to know how many cores are available on the platform. This PCD is expected to contain this number.

2012-09-28ArmPlatformPkg/PrePi: Moved Exception Vector Table to ArmPkg/DebugAgentBaseLiboliviermartin
In case a DebugAgent library is supported for a specific debugger, we would expect the exception be caught by DebugAgentLib. The DebugAgentBaseLib exposes the cause of the exception to the user in the Serial Terminal.

2012-05-02ArmPkg/ArmCpuLib: Replaced complex functions ArmCpuSynchronizeWait & ↵oliviermartin
ArmCpuSynchronizeSignal by sev & wfe Previsouly the synchronization of MpCore was using the SGI (Software Generated Interrupt) to synchronize MpCore during the early boot. This commit replaced this mechanism by the more appropriate SEV/WFE instructions (Send/Wait Event instructions). That also eases the port to a new cpu/platform.

2012-05-02ArmPlatformPkg: Renamed and Invoked earlier ArmPlatformNormalInitialize()oliviermartin
- ArmPlatformNormalInitialize() has been renamed into ArmPlatformInitialize() - Make the function be called at the early stage of the PEI phase as some platforms require their interconnects or clocks to be initialize before any access to Timers or UARTs.

2011-09-22ArmPkg: Create MpCoreInfo PPI and HOB to describe CPU Cores on a MPCore platformoliviermartin
These info are: - ClusterId, CoreId - MailBox Set/Get/Clear address git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@12423 6f19259b-4bc3-4df7-8a09-765794883524
2011-09-22ArmPlatformPkg: Introduce ArmPlatformGlobalVariableLiboliviermartin
This library hides where the 'XIP' Global Variable are located in the memory. It is expected the Sec/PrePi modules define the Global Variable area through the GlobalVariable HOB. The ArmPlatformGlobalVariableLib library allows access to global variables by their offsets in this region. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@12420 6f19259b-4bc3-4df7-8a09-765794883524
2011-09-22ArmPlatformPkg/PrePi: Removed the dependency on 'PcdCPUCoresNonSecStackBase'oliviermartin
In PrePi the StackBase is automatically calculated from the top of the memory. The information is now passed from the assembly files to the C code. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@12418 6f19259b-4bc3-4df7-8a09-765794883524
2011-09-22ArmPlatformPkg: Changed memory model for the stacksoliviermartin
In the previous version, every cores had the same stack size. To avoid to waste memory with secondary core stacks, the primary core stack size is now different from the secondary cores stack size. These are the Stack PCDs and their default values: gArmPlatformTokenSpaceGuid.PcdCPUCoresSecStackBase|0 gArmPlatformTokenSpaceGuid.PcdCPUCoreSecPrimaryStackSize|0x10000 gArmPlatformTokenSpaceGuid.PcdCPUCoreSecSecondaryStackSize|0x1000 gArmPlatformTokenSpaceGuid.PcdCPUCoresSecMonStackBase|0 gArmPlatformTokenSpaceGuid.PcdCPUCoreSecMonStackSize|0x1000 gArmPlatformTokenSpaceGuid.PcdCPUCoresStackBase|0 gArmPlatformTokenSpaceGuid.PcdCPUCorePrimaryStackSize|0x10000 gArmPlatformTokenSpaceGuid.PcdCPUCoreSecondaryStackSize|0x1000 git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@12415 6f19259b-4bc3-4df7-8a09-765794883524
2011-09-22ArmPlatformPkg: Introduce Primary core macrosoliviermartin
On MpCore system, the primary core can now be any core of the system. To identify the primary core, you can use 'gArmTokenSpaceGuid.PcdArmPrimaryCoreMask' and 'gArmTokenSpaceGuid.PcdArmPrimaryCore'. 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. The helper macros are: IS_PRIMARY_CORE(MpId), GET_CORE_ID(MpId), GET_CLUSTER_ID(MpId), GET_CORE_POS(MpId), PRIMARY_CORE_ID. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@12412 6f19259b-4bc3-4df7-8a09-765794883524

2011-08-18ArmPlatformPkg/PrePi: Removed second initialization of DebugAgenLiboliviermartin
This second initialization does not make sense in this context. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@12164 6f19259b-4bc3-4df7-8a09-765794883524

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

2011-07-01ArmPlatformPkg/PrePi: Add support for PrePi moduleoliviermartin
This module should handle the Pre PI phase before the DXE core is executed when there is no PEI Core support. It declares the required information needed by the DXE core through HOBs. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@11949 6f19259b-4bc3-4df7-8a09-765794883524
