* ArmPkg/CpuDxe: use private copy of GetRootTranslationTableInfo()Ard Biesheuvel2020-04-021-7/+0
| | | | | | | | | | | | | | | | | Before getting rid of GetRootTranslationTableInfo() and the related LookupAddresstoRootTable() in AARCH64's version of ArmMmuLib, add a version of the former to CpuDxe, which will be its only remaining user. While at it, simplify it a bit, since in the CpuDxe cases, both OUT arguments are always provided. Note that this removes the declaration of GetRootTranslationTableInfo() as well, but this is a declaration that is private to CpuDxe, and it really doesn't belong here in the first place. Since ArmMmuLib's version of GetRootTranslationTableInfo() is going to be replaced shortly anyway, don't bother moving this .h declaration elsewhere.

* ArmPkg: move ARM version of SetMemoryAttributes to ArmMmuLibArd Biesheuvel2017-03-071-13/+1
| | | | | | | | | | | | | | | ... where it belongs, since AARCH64 already keeps it there, and non DXE users of ArmMmuLib (such as DxeIpl, for the non-executable stack) may need its functionality as well. While at it, rename SetMemoryAttributes to ArmSetMemoryAttributes, and make any functions that are not exported STATIC. Also, replace an explicit gBS->AllocatePages() call [which is DXE specific] with MemoryAllocationLib::AllocatePages().

* ArmPkg/CpuDxe: ignore attribute changes during SyncCacheConfig()Ard Biesheuvel2017-02-281-0/+1
| | | | | | | | | | | | | | | To prevent the initial MMU->GCD memory space map synchronization from stripping permissions attributes [which we cannot use in the GCD memory space map, unfortunately], implement the same approach as x86, and ignore SetMemoryAttributes() calls during the time SyncCacheConfig() is in progress. This is a horrible hack, but is currently the only way we can implement strict permissions on arbitrary memory regions [as opposed to PE/COFF text/data sections only] Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Reviewed-by: Jiewen Yao <jiewen.yao@intel.com> Reviewed-by: Leif Lindholm <leif.lindholm@linaro.org>
* ArmPkg/CpuDxe: remove VirtualUncachedPages protocol and implementationArd Biesheuvel2017-02-231-3/+0
| | | | | | | | | | Virtual uncached pages are simply pages that are aliased using mismatched attributes, which is not allowed by the ARM architecture. So remove the protocol and its implementation.

* ArmPkg/ArmMmuLib: AARCH64: add support for modifying only permissionsArd Biesheuvel2017-02-211-8/+0
| | | | | | | | | | | | | | Since the new DXE page protection for PE/COFF images may invoke EFI_CPU_ARCH_PROTOCOL.SetMemoryAttributes() with only permission attributes set, add support for this in the AARCH64 MMU code. Move the EFI_MEMORY_CACHETYPE_MASK macro to a shared location between CpuDxe and ArmMmuLib so we don't have to introduce yet another definition.

Including a light weight command line shell. BeagleBoardPkg - Platform specifics for BeagleBoard. SD Card works, but USB has issues.
