2016-09-08ArmPkg ArmPlatformPkg ArmVirtPkg: ARM GICv2/v3 Base Address width fix-upDennis Chen
According to the ACPI 6.0/6.1 spec, the physical base address of GICC, GICD, GICR and GIC ITS is 64-bit. So change the type of the various GIC base address PCDs to 64-bit, and fix up all users.

The RVCT .asm files include AsmMacroIoLib.h only for the definition of LoadConstantToReg (), which makes it tedious to make change to that file without the risk of making the RVCT assembler unhappy. So simply replace LoadConstantToReg() with mov32, which does the right thing in all cases.

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.

2015-11-27ArmPlatformPkg/PrePeiCore: add missing entries to AArch64 vector tableArd Biesheuvel
The PrePeiCore vector table for AArch64 mode is only half populated. However unlikely, if exceptions from lower exception levels are ever taken, they should be reported correctly, rather than causing a recursive undefined instruction fault on the zero padding that was introduced by commit SVN r18904 ("ArmPkg/ArmPlatformPkg: position vectors relative to base"). So add the missing entries, and wire them up to the default handler.

2015-11-19ArmPkg/ArmPlatformPkg: position vectors relative to baseMark Rutland
We currently rely on .align directives to ensure that each exception vector entry is the appropriate offset from the vector base address. This is slightly fragile, as were an entry to become too large (greater than 32 A64 instructions), all following entries would be silently shifted until they meet the next alignment boundary. Thus we might execute the wrong code in response to an exception. To prevent this, introduce a new macro, VECTOR_ENTRY, that uses .org directives to position each entry at the precise required offset from the base of a vector. A vector entry which is too large will trigger a build failure rather than a runtime failure which is difficult to debug. For consistency, the base and end of each vector is similarly annotated, with VECTOR_BASE and VECTOR_END, which provide the necessary alignment and symbol exports. The now redundant directives and labels are removed.

2015-08-07ArmPlatformPkg/PrePeiCore: constify PPI globalsArd Biesheuvel
Since PrePeiCore's .text section contains an AARCH64 exception vector table, its 2 KB alignment propagates to other sections as well. Since this is a SEC module, it should not have any writable data in the first place, so change some non-const PPI globals to const. The resulting binary has no .data section at all, which saves 2 KB in the XIP image.

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
2011-09-22ARM Packages: Rename PcdNormal* into Pcd* PCDsoliviermartin
The denomination 'Normal' was used to make reference to the 'Normal' or 'Non Secure' or 'Non Trusted' world. To avoid confusion, this prefix has been removed from PCDs to define the normal world. The PCDs explicitely related to the Secure/Trusted World continue to have the 'Sec' prefix. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@12416 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
