2018-04-23ARM/VExpressPkg: New DP500/DP550/DP650 platform libraryGirish Pathak
This change adds LcdPlatformLib implementation for Arm Mali DP500/DP500/DP650 display processors for models (with DP550 support). NOTE: Versions for actual hardware are liable to require extra handling for clock input changes, etc. Contributed-under: TianoCore Contribution Agreement 1.1 Signed-off-by: Girish Pathak <girish.pathak@arm.com> Signed-off-by: Evan Lloyd <evan.lloyd@arm.com> Reviewed-by: Leif Lindholm <leif.lindholm@linaro.org>
2018-04-23ARM/VExpressPkg: Set EFI_MEMORY_XP flag on GOP framebufferGirish Pathak
The framebuffer memory is set with flag EFI_MEMORY_WC (uncached, unbuffered) which causes framebuffer memory with eXecute bit set. Framebuffer memory having executable bit set is a security hazard. This fix adds EFI_MEMORY_XP flag to avoid this. Unfortunately function gDS->SetMemorySpaceAttributes() causes assertion due to unsupported EFI_MEMORY_XP type. Therefore this fix replaces gDS->SetMemorySpaceAttributes() with Cpu->SetMemoryAttributes().

2018-04-23ARM/VExpressPkg: Reserving framebuffer at buildGirish Pathak
This change uses two PCDs, PcdArmLcdFrameBufferBase and PcdArmLcdFrameBufferSize introduced in correspondiong EDK2 patch to reserve framebuffer in DRAM if these values are defined in platform specific DSC file, avoiding the need to allocate dynamically. This allows the framebuffer to appear as "I/O memory" outside of the normal RAM map, which is similar to the "VRAM" case.

2018-04-23ARM/VExpressPkg: Allocate framebuffer using EfiReservedMemoryTypeGirish Pathak
As per the UEFI specification(2.7) section 12.9, the GOP framebuffer memory can be accessed in the pre-boot and the post boot phase (by OS) Therefore the memory type EfiBootServicesData which may no longer exist after ExitBootServices is incorrect for the framebuffer memory allocation. Change EfiBootServicesData with EfiReservedMemoryType so that allocated memory can be accessed in the post boot phase.

2018-04-23ARM/VExpressPkg: PL111 and HDLCD: Add PCD to select pixel formatGirish Pathak
Current HDLCD and PL111 platform libraries do not support display modes with PixelBlueGreenRedReserved8BitPerColor format, i.e. because of historical confusion, they do not support the UEFI default PixelBlueGreenRedReserved8BitPerColor LcdPlatformLib for PL111, LcdPlatformQueryMode function returns the pixel format as PixelRedGreenBlueReserved8BitPerColor which is wrong, because that does not match the display controller's pixel format which is set to BGR in PL111Lcd GOP driver. Also it is not possible to configure pixel format as RGB/BGR for the display modes for a platform at build time. This change adds PcdGopPixelFormat to configure pixel format as PixelRedGreenBlueReserved8BitPerColor or PixelBlueGreenRedReserved8BitPerColor or PixelBitMask. With this change, pixel format can be selected in the platform specific .dsc file for all supported display modes. Support for PixelBitMask is not implemented in PL111 or HDLCD GOP driver, hence HDLCD and PL111 platform libraries will return error EFI_UNSUPPORTED if PcdGopPixelFormat is set to PixelBitMask. Indeed, it is not clear what selecting PixelBitMask might mean, but the option is allowed as it might suit a custom platform.

2018-04-23ARM/VExpressPkg: Redefine LcdPlatformGetTimings functionEvanLloyd
The LcdPlatformGetTimings interface function takes similar sets of multiple parameters for horizontal and vertical timings which can be aggregated in a common data type. This change defines a structure SCAN_TIMINGS for this which can be used to describe both horizontal and vertical scan timings, and accordingly redefines the LcdPlatformGetTiming interface, greatly reducing the amount of data passed about. Similarly the mode definition tables are also changed to use this data type and thus enable pass through access.
