Ard Biesheuvel 5a9b3eb8e5 ArmPlatformPkg/PL011SerialPortLib: use untyped PCD for register base
Use an untyped PCD reference for PcdSerialRegisterBase, so that the
library gets built without hardcoded values, permitting modules to
override the default serial port. This allows SerialDxe to use a
different serial port from the one used for DEBUG output (which
often gets occluded due to the console driver clearing the screen).

Udit Kumar cbba5ca104 ArmPlatformPkg: PL011 Dynamic clock freq Support
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

Girish Pathak b99f81268a ArmPlatformPkg: New DP500/DP550/DP650 GOP driver
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.

Girish Pathak 268aad6744 ArmPlatformPkg: PCD to swap red/blue format for HDLCD
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.

Girish Pathak fe787dfb0f ArmPlatformPkg: Add PCD to select pixel format
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.

from the timezone setting, as well as flicking the EFI_TIME_IN_DAYLIGHT

This means we need to disregard the DST setting if the timezone is

Ard Biesheuvel 3858b4a1ff ArmPlatformPkg/PlatformIntelBdsLib: don't clobber ConSplitter handle
The InitializeConsolePipe() routine takes care to only set its output
argument *Interface if it is not already set, to prevent overwriting
the ConSplitter interface pointer that may have already been assigned.

However, the associated OUT argument 'Handle' is clobbered by the
subsequent unnecessary LocateDevicePath() invocation, which should
similarly be made dependent on whether *Interface has been set
already.

Ard Biesheuvel 91231b55d5 ArmPlatformPkg/ArmPlatformStackLib: use callee preserved registers
The entry code in ArmPlatformStackSet () is a 1:1 transliteration of the
ARM version, which uses the callee preserved registers r3 - r7 (*) to
preserve the function arguments and the link register across a call to
ArmPlatformIsPrimaryCore ().

However, x3 - x7 are not callee preserved on AARCH64, and so we should use
registers >= x19 instead. While we're at it, drop an unnecessary preserve
of the link register, and simplify/deobfuscate the calculation of the
secondary stack position.

(*) Note that r3 is not actually a callee saved register even on ARM.

Alexei a4bcf0bcdd ArmPlatformPkg: Remove UINTN cast when setting BaudRate.
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);
