Add the DisplayUpdateProgressLib class that is used
to inform the user of progress during updates of
firmware images in firmware devices. A platform
specific instance of this library can be used to
customize how the user is informed of progress.
Add the EDK II Firmware Management Progress Protocol.
This is an optional protocol that must be installed
onto the same handle as a Firmware Management Protocol.
This new protocol provides the color of a progress
bar that allows different firmware devices to use
different colors during a firmware update. It also
provides a watchdog timer value in seconds that is
armed each time the Progress() service passed
into Firmware Management Protocol SetImage()
is called.

Add Translation field to PCI_ROOT_BRIDGE_APERTURE. Translation is used
to represent the difference between device address and host address,
if they are not the same on some platforms.
In UEFI 2.7, "Address Translation Offset" is "Offset to apply to the
Starting address to convert it to a PCI address". This means:
Translation = device address - host address
So we also use the above calculation for this Translation field to
keep consistent.

Add support for platform specific reset filters and platform
specific reset handlers to ResetSystem(). A filter may modify
the reset type and reset data and call ResetSystem() with the
modified parameters. A handler performs the reset action.
The support for platform specific filters and platform specific
handlers is based on the Reset Notification feature added to the
UEFI 2.7 Specification.
Platform specific reset filters are processed first so the final
reset type and reset data can be determined. In the DXE Phase
The UEFI Reset Notifications are processed second so all UEFI
Drivers that have registered for a Reset Notification can perform
any required clean up actions. The platform specific reset
handlers are processed third. If there are no registered
platform specific reset handlers or none of them reset the
platform, then the default reset action based on the
ResetSystemLib is performed.
In the PEI Phase, filters and handlers are registered through
the following 2 PPIs that are based on
EFI_RESET_NOTIFICATION_PROTOCOL.
* gEdkiiPlatformSpecificResetFilterPpiGuid
* gEdkiiPlatformSpecificResetHandlerPpiGuid

Many ARM based SoCs have integrated SDHCI controllers, and often,
these implementations deviate in subtle ways from the pertinent
specifications. On the one hand, these deviations are quite easy
to work around, but on the other hand, having a collection of SoC
specific workarounds in the generic driver stack is undesirable.
So let's introduce an optional SD/MMC override protocol that we
can invoke at the appropriate moments in the device initialization.
That way, the workaround itself remains platform specific, but we
can still use the generic driver stack on such platforms.

BaseTools will generate the optimized PCD database to save the image size
at build time for multiple SKUs. The optimized PCD database layout will be like
below, the PCD database will be composed of the full default SKU data
(PCD_DATABASE_INIT) and the non-default SKU delta data(PCD_DATABASE_SKU_DELTA).
PCD driver will build HOB to store the full default SKU data, and patch HOB
data based on non-default SKU delta data for the SKU set by SetSku(),
it can save memory resource at boot time.
//
// PCD database layout:
// +---------------------------------+
// | PCD_DATABASE_INIT (DEFAULT SKU) |
// +---------------------------------+
// | PCD_DATABASE_SKU_DELTA (SKU A) |
// +---------------------------------+
// | PCD_DATABASE_SKU_DELTA (SKU B) |
// +---------------------------------+
// | ...... |
// +---------------------------------+
//
BaseTools, PCD database and driver updates are needed for this proposal.
For single SKU (default) case, this proposal is expected to have no impact.
For multi-SKU case, PCD database format will be changed.
So, PcdDataBase Version is also updated from 6 to 7.

InitializeCpuExceptionHandlersEx (
IN EFI_VECTOR_HANDOFF_INFO *VectorInfo OPTIONAL,

By default, this method should include all functionalities implemented by

This is could be done by calling InitializeCpuExceptionHandlers() directly
in this method besides the extra works.
InitData is optional and its use and content are processor arch dependent.
The typical usage of it is to convey resources which have to be reserved

This patch is to follow RFC3021 which allows to use 31-bit mask
in point-to-point link.
If a 31-bit subnet mask is assigned to a point-to-point link, it
leaves the <Host-number> with only 1 bit. Consequently, only two
possible addresses may result:
{<Network-number>, 0} and {<Network-number>, -1}
These addresses have historically been associated with network and
broadcast addresses (see Section 2.2). In a point-to-point link with
