Some platform support dynamic clocking, which is controlled by some

This patch implements support for dynamic frequency for PL011 uart.
This patch implements default lib, which is using Pcd. Platform which

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.

Currently framebuffer memory is either reserved in special VRAM or
dynamically allocated using boot services memory allocation functions.
When allocated using boot services calls the memory has to be allocated
as EfiBootServicesData. Unfortunately failures have been seen with this
case. There is also an unfortunate lack of control on the placement of
the framebuffer.
This change introduces two PCDs, PcdArmLcdFrameBufferBase and
PcdArmLcdFrameBufferSize which enable build time reservation of the
framebuffer, 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.
This change has no impact on current code, only enables the option
of build time reservation of framebuffers.

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.

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.

Juno has several serial ports, one of which may be used for a remote
debug interface (e.g. gdb, WinDbg). The debug serial port needs to
be distinct from that used for UEFI trace to prevent corruption of
debugger protocol messaging.
The UEFI spec requires that serial devices be initialised to default
settings. (11.8 Serial I/O Protocol - "The default attributes for all
UART-style serial device interfaces are: 115,200 baud, ..."
and 17.3.3 EFI Debugport Variable - "These defaults must be used in the
absence of a DEBUGPORT variable...")
This change adds initialization of the serial device reported in the
ACPI DBG2 table. The initialisation is done early in the boot to allow
the possibility of remote debug of UEFI itself.
NOTE: This is functionally dependent on the DBG2 table being updated in
OpenPlatformPkg, but is required as a precursor to that change.

The NorFlashDxe uses an explicit 'BEFORE xxx' Depex declaration to
ensure that it is dispatched before VariableRuntimeDxe, and uses the
file GUID of the latter as 'xxx' explicitly to accomplish that.
However, when enabling UEFI Secure Boot, this breaks down since the
authenticated VariableRuntimeDxe is a completely separate driver, with
a different GUID. Also, the hardcoded dependency on gEfiVariableGuid,
which is not used under UEFI Secure Boot, needs to be factored out in
order to allow this driver to be used.
So clone NorFlashDxe.inf into NorFlashAuthenticatedDxe.inf, and fix
up the dependencies so they refer to gEfiAuthenticatedVariableGuid and
SecurityPkg/VariableAuthenticated/RuntimeDxe/VariableRuntimeDxe.inf
instead.
