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.

2014-08-19ArmPkg/BdsLib: Prevent a hang in BdsConnectDevicePath() when a sub-device ↵Olivier Martin
path is not found Some device paths were making BdsConnectDevicePath() hang. To prevent these hangs we check if the handle returned by gBS->LocateDevicePath() is the same after each iteration. An example of a device path that hangs: PciRoot(0x0)/Pci(0x1,0x0)/USB(0x0,0x0)/USB(0x3,0x0)/HD(...) The connect controller function manages to find PciRoot()/Pci(0x1,0x0) but the USB driver does not produce USB(0x0,0x0)/USB(0x3,0x0) and returns EFI_SUCCESS on its initialization.

2014-08-04ArmPkg/ArmSmcLib: Fixed SMC helper functionsOlivier Martin
The SMC helper functions were buggy as they were assuming that the values in x1-x7 registers were preserved across an SMC call, which is not the case. This patch fixes this issue. It also simplifies the code by providing only 1 version of the SMC helper function. We used to have 4 versions depending on the number of arguments. The problem with this approach was that the number of arguments also dictated the number of return values, which is completely unrelated. E.g. you can have an SMC call that takes 1 argument but returns 4 values.

2014-07-29ArmPkg: Remove BasePeCoffLibHarry Liebel
ArmPkg contains unused and outdated code for runtime PE/COFF image relocation. - Use the version in MdePkg instead. - Remove references to this package from BeagleBoardPkg. ArmPkg/BasePeCoffLib was added to deal with MOVT instruction that was not part of the PE/COFF specification at that time.

2014-07-15ARM Packages: Force the SEC modules to be 2K aligned for AArch64Olivier Martin
The AArch64 Vector Table must be aligned on a 2K boundary. The FDF specification does not support 2K alignment but support 4K. A clear comment has been added to help integrator to understand why the assertion fails when porting to a new AArch64 platform.

2014-07-15ArmPkg/BdsLib: Removed PSCI discoverability from the Linux loaderOlivier Martin
Some platforms might decide to not support PSCI in their FDT-aware Linux system even if their firmware supports it. It is the responsibility of the platform engineer to provide the appropriate FDT. The PCD gArmTokenSpaceGuid.PcdArmPsciSupport is not required anymore.

In some case, the size of the downloaded TFTP image cannot be known. An arbitrary larger buffer is allocated to receive the image. We need to make sure when we free the buffer we free the size of the allocated buffer and not the size of the actual image.
