2015-08-19ArmPkg: remove ARMv6 support codeArd Biesheuvel
No platforms use the ARMv6 (ARM11) support code anymore. In fact, the only reference to it in ArmPkg.dsc was commented out by Andrew in SVN r11298 (2011-02-03) so it may well be broken. So remove it.

2015-08-10ArmPkg/GicV3: use GICv3 generic sysreg names only for GNU asArd Biesheuvel
The GNU assembler extends the generic notation for IMPLEMENTATION DEFINED system registers to support any system register, so that system registers defined by newer versions of the architecture can still be used by older versions of the toolchain. Clang before v3.6 supports the generic notation, but does not support this extension, nor does it need to in the particular case of the GICv3 support code, since it knows the GICv3 registers by their architectural names. So only redefine their real names to their generic aliases if we are not using clang.

2015-07-28ArmPkg: split off ArmGicArchLib from ArmGicLibArd Biesheuvel
The current implementation of ArmGicGetSupportedArchRevision () that is used by all ARM platforms is entirely stateless (in order to support being executed from flash) so it needs to interrogate the hardware for the supported GIC revision upon each invocation. However, this statelessness is only needed for SEC type modules; in all other cases, we could easily determine the GIC revision once, and store the result in a global variable. In preparation of having separate early and normal versions, this patch introduces the ArmGicArchLib library class and default implementation, and moves the existing ArmGicGetSupportedArchRevision () into it.

Before splitting off ArmGicArchLib and moving it out of ArmPkg/Drivers/ArmGic into ArmPkg/Library, make sure that the GIC specific declarations it depends on are not hidden away in local headers "GicV2/GicV2Lib.h" and "GicV3/GicV3Lib.h". So merge them with <Library/ArmGicLib.h>. This is entirely appropriate, since this is not a header that declares a public interface into ArmGicLib, but defines implementation internals.

Accesses to system registers are disproportionately heavy-weight when executed under virtualization, since each one involves two world switches (from guest to host and back again). So change the sequence that enables the GIC SRE interface so that it performs only a single sysreg read to test whether the SRE interface is enabled already, and only performs a write and an additional read if that turns out not to be the case.

2015-04-14ArmPkg: remove cache maintenance by VA operation range size thresholdArd Biesheuvel
This removes the range size threshold for virtual address based cache maintenance instructions that operate on VA ranges to be 'promoted' to use set/way instructions. Doing so is unsafe: set/way operations are fundamentally different from VA operations, and really only suitable for cleaning or invalidating a cache when turning it on or off. To quote the ARM ARM (DDI0487A_d G3.4): """ Since the set/way instructions are performed only locally, there is no guarantee of the atomicity of cache maintenance between different PEs, even if those different PEs are each performing the same cache maintenance instructions at the same time. Since any cacheable line can be allocated into the cache at any time, it is possible for [a] cache line to migrate from an entry in the cache of one PE to the cache of a different PE in a manner that the cache line avoids being affected by set/way based cache maintenance. Therefore, ARM strongly discourages the use of set/way instructions to manage coherency in coherent systems.

2015-02-02ArmPkg: ArmArchTimerLib: conditionally rebase to actual timer frequencyLaszlo Ersek
Allow a platform to set PcdArmArchTimerFreqInHz to zero, and consider it a request to use the actual timer frequency. No global variable is introduced, so that the library can be used in PEIMs that execute from flash.

2014-12-12ArmPkg/AsmMacroIoLib: Fixed the global variables initializationOlivier Martin
The top of the stack always points to 'stack_base + stack_size'. But the stack pointer is decremented before writing to the stack. It means the top byte of the stack is actually 'stack_base + stack_size - 1'. The initialization should also decrement the stack pointer before zero'ing the memory (pre-indexed addressing).

The memory reserved to load the device tree is over-allocated when UEFI loads the blob to update the device tree with additional information such as the command line, the initrd, etc. This change ensures the total size declared by the device tree matches the actual data (and not the over-allocated size value).

2014-11-13ArmPkg/ArmGicLib: select GICv2 mode if SRE is present but unavailableArd Biesheuvel
Even if the CPU id registers indicate hardware support for the System Register interface to the GIC, higher exception levels may disable that interface and only allow access through MMIO. So move the enabling of the SRE bit to the GIC version detection routine: if we trigger an exception, we would have anyway at a later stage, so the net effect is the same. However, if setting the bit doesn't stick, it means we can switch to MMIO and proceed normally otherwise.
