2017-04-06ArmPlatformPkg/PL111LcdArmVExpressLib: use write-combine mapping for VRAMArd Biesheuvel
Replace the uncached memory mapping of the framebuffer with a write- combining one. This improves performance, and avoids issues with unaligned accesses and DC ZVA instructions performed by the accelerated memcpy/memset routines. Instead of manipulating the memory attributes directly, use the SetMemorySpaceAttributes() DXE services, which validates the attributes against the capabilities of the region before making the actual change.

2017-04-06ArmPlatformPkg/FVP: map motherboard VRAM as uncached memoryArd Biesheuvel
The VRAM of the PL111 on the FVP Base/Foundation models is described as device memory rather than uncached memory, which is not an accurate description of the nature of the region (i.e., a framebuffer), and may result in problems when using accelerated string routines to access the region, since this may legally involve unaligned accesses or DC ZVA instructions, which are not allowed on device mappings. So split of the 8 MB VRAM region into a separate region, and map it using memory attributes.

ARM TZASC-380 IP provides a mechanism to split memory regions being protected via it into eight equal-sized sub-regions. A bit-setting allows the corresponding subregion to be disabled. Several NXP/FSL SoCs support the TZASC-380 IP block and allow the DDR connected via the TZASC to be partitioned into regions having different security settings and also allow subregions to be disabled. This patch enables this support and can be used for SoCs which support such a partition of DDR regions.

2016-10-24ArmPlatformPkg/PrePi: avoid global variable write to mSystemMemoryEndArd Biesheuvel
The global variable mSystemMemoryEnd is initialized by PrePi only if it has not been initialized by ArmPlatformPeiBootAction(). This allows platforms executing under, e.g., ARM Trusted Firmware to dynamically reserve a window at the top of memory that will be used by the secure firmware. However, PrePi is a SEC module, and writing to a global variable violates the SEC constraints, since SEC and PEI may execute from NOR flash. So instead, initialize mSystemMemoryEnd statically. This will ensure it holds the correct value for all implementations where the value is not overridden, but still allows it to be overridden during the call to ArmPlatformPeiBootAction(). Note that this patch also fixes a latent bug on 32-bit platforms where a value of mSystemMemoryEnd exceeding 4 GB would be truncated to 32-bits rather than limited to (4 GB - 1) Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Acked-by: Laszlo Ersek <lersek@redhat.com> Tested-by: Ryan Harkin <ryan.harkin@linaro.org> Reviewed-by: Leif Lindholm <leif.lindholm@linaro.org>

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.

2016-08-04ArmPlatformPkg: change PcdBdsLinuxSupport default valueDaniil Egranov
The built-in Linux Loader is obsolete and not included in most builds. The patch sets the PcdBdsLinuxSupport default value to FALSE and prevents ArmBds from looking for built-in Linux Loader by default and ASSERTing when it cannot be found. Platforms which still using built-in loader have to set this PCD in their platform description file.
