* ArmPlatformPkg: Include PL011UartClock LibUdit Kumar2018-06-152-2/+4
| | | | | | | | | This patch gets PL011 baud rate clock from pl011 uart clock lib instead of Pcd. Contributed-under: TianoCore Contribution Agreement 1.1 Signed-off-by: Udit Kumar <udit.kumar@nxp.com> Reviewed-by: Ard Biesheuvel <ard.biesheuvel@linaro.org>
* ArmPlatformPkg: PL011 Dynamic clock freq SupportUdit Kumar2018-06-132-0/+59
| | | | | | | | | | | | | | | Some platform support dynamic clocking, which is controlled by some jumper setting or hardware registers. Result of that is that PCD PL011UartClkInHz would need to be updated for frequency change. This patch implements support for dynamic frequency for PL011 uart. This patch implements default lib, which is using Pcd. Platform which needs dynamic clocking needs implement PL011UartClockLib Contributed-under: TianoCore Contribution Agreement 1.1 Signed-off-by: Udit Kumar <udit.kumar@nxp.com> Reviewed-by: Ard Biesheuvel <ard.biesheuvel@linaro.org>
* ArmPlatformPkg: New DP500/DP550/DP650 GOP driverGirish Pathak2018-04-233-0/+695
| | | | | | | | | | | | | | | | | | | | | | This change adds support for the ARM Mali DP500/DP500/DP650 display processors using the GOP protocol. It has been tested on FVP base models + DP550 support. This change adds platform independant LcdHwLib library. A corresponding platform specific library will be submitted to edk-platforms/Platform/ARM/VExpressPkg. This change does not modify functionality provided by PL111 or HDLCD. This LcdHwLib implementation should be suitable for those platforms that implement ARM Mali DP500/DP550/DP650 replacing PL111/HDLCD. Only graphics layer of the ARM Mali DP is configured for rendering the RGB/BGR format frame buffer to satisfy the UEFI GOP requirements Other layers e.g. video layers are not configured.

* ArmPlatformPkg: PCD to swap red/blue format for HDLCDGirish Pathak2018-04-232-2/+13
| | | | | | | | | | | | | | | | | | | This change adds a new PCD PcdArmHdlcdSwapBlueRedSelect to swap values for HDLCD RED_SELECT and BLUE_SELECT registers on platforms where blue and red hardware lines are swapped. If set to TRUE in the platform dsc, HDLCD library will swap the values while setting RED_SELECT and BLUE_SELECT registers. The default value of the PCD is FALSE. NOTE: The motive for this is that a discrepancy in the Red/Blue lines exists between some VersatileExpress platforms. Rather than have divergent code, this build switch allows a simple, pragmatic solution.

* ArmPlatformPkg: Add PCD to select pixel formatGirish Pathak2018-04-232-37/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 format In LcdPlatformLib for PL111, LcdPlatformQueryMode 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 LcdHwLib. 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 LcdHwLib libraries, 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.

* ArmPlatformPkg: Remove UINTN cast when setting BaudRate.Alexei2016-10-111-1/+1
| | | | | | | | | | | | | | | SerialPortInitialize() set the BaudRate variable (type UINT64) as: BaudRate = (UINTN)FixedPcdGet64 (PcdUartDefaultBaudRate); This commit fixes a potential problem on ARM 32-bit builds, where the UINTN type is defined as UINT32, by removing the cast: BaudRate = FixedPcdGet64 (PcdUartDefaultBaudRate); Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Alexei Fedorov <alexei.fedorov@arm.com> Signed-off-by: Evan Lloyd <evan.lloyd@arm.com> Reviewed-by: Leif Lindholm <leif.lindholm@linaro.org>

| | | | | | | | | | | Correct some obviously incorrect comments that have invalid details for the returned values. (Copy /Paste problem?) There are no functional changes in this commit.

| | | | | | | | | | | According to the ACPI 6.0/6.1 spec, the physical base address of GICC, GICD, GICR and GIC ITS is 64-bit. So change the type of the various GIC base address PCDs to 64-bit, and fix up all users.

| | | | | | | | | | | | | Annotate functions with ASM_FUNC() so that they are emitted into separate sections. While we're at it, replace some inefficient uses of LoadConstantToReg(), and remove the workaround that was added to allow conditional branches to functions with external linkage.
