2016-09-08ArmPlatformPkg: remove EFI_MEMORY_UC attribute from normal memoryArd Biesheuvel
On ARM systems, mapping normal memory as device memory may have unintended side effects, given that unaligned accesses or loads and stores with special semantics (e.g., load/store exclusive) may fault or may not work as expected. Similarly, DC ZVA instructions are only supported on normal memory, not device memory. So remove the EFI_MEMORY_UC attribute that we set by default on system RAM. If any region requires this attribute, it is up to the driver to set this attribute, and to ensure that no offending operations are performed on it.

Switch all users of ArmLib that depend on the MMU routines to the new, separate ArmMmuLib. This needs to occur in one go, since the MMU routines are removed from ArmLib build at the same time, to prevent conflicting symbols.

2016-02-02ArmPlatformPkg: Rectify file modesEvan Lloyd
Problems have been encountered because some of the source files have execute permission set. This can cause git to report them as changed when they are checked out onto a file system with inherited permissions. This has been seen using Cygwin, MinGW and PowerShell Git. This patch makes no change to source file content, and only aims to correct the file modes/permissions.

For 32-bit ARM platforms, it is essential that system memory starts below the 4 GB limit, since that is the only memory we can address using the UEFI spec mandated 1:1 mapping.

2015-04-14ArmPlatformPkg: do not fulfil MemoryInitPeiLib dependency directly via .c fileArd Biesheuvel
MemoryInitPeim short-circuits its MemoryInitPeiLib dependency by including the .c file directly.

2014-09-09ArmPkg,ArmPlatformPkg: Allow dynamic PCDs for memory base and sizeArd Biesheuvel
This changes the definition and a bunch of references to gArmTokenSpaceGuid.PcdSystemMemoryBase and gArmTokenSpaceGuid.PcdSystemMemorySize so they can be declared as dynamic PCDs by the platform. Also, move the non-SEC call to ArmPlatformInitializeSystemMemory() earlier, so a platform has a chance to set these PCDs before they are first referenced. The purpose is allowing dynamically instantiated virtual machines to declare the system memory by passing a device tree.

2013-09-16ArmPlatformPkg/MemoryInitPei: AARCH64 fix memory address calculationsGarrett Kirkendall
At least for AARCH64 currently, SystemMemoryTop and FdTop can overflow while adding the 32-bit PCDs together. The resulting value loses the upper 32-bits. Cast each of the values to EFI_PHYSICAL_ADDRESS size before doing the addition to prevent erroneous overflow. There is currently no 32-bit platform in EDKII open source that will overflow and this change would not fix that problem anyway.

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
2011-07-06ArmPlatformPkg: 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

2011-03-31ArmPlatformPkg/ArmPlatformLib: Move the UEFI memory partionning to MemoryInitPeioliviermartin
Formerly, each platform was responsible to declare the location of its UEFI memory region (used by PEI and DXE Foundations). The ArmPlatformLib was also declaring every region of its partitionned system memory with a System Resource HOB. In this new model, the MemoryInit expects the system memory to be declared with the PCDs gArmTokenSpaceGuid.PcdSystemMemoryBase/Size. These PCDs declare the largest continuous DRAM region. Additional regions can be declared with the ArmPLatformLib function ArmPlatformGetAdditionalSystemMemory(). Now, it is the PEIM that partitions the system memory for every platform. It installs a region of the size PcdSystemMemoryUefiRegionSize (default 128MB) for the PEI permanent memory at the top of the DRAM region. And a region of gArmPlatformTokenSpaceGuid.PcdSystemMemoryFixRegionSize (default 128MB) is declared at the base of the system memory. This region is used for the allocation that requires fixed address or have some constraints on their locations. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@11481 6f19259b-4bc3-4df7-8a09-765794883524
