These 2 library instances should be the default ResetSystemLib

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
In the DXE Phase, filters and handlers are registered through
the following 2 Protocols that are based on
EFI_RESET_NOTIFICATION_PROTOCOL.
* gEdkiiPlatformSpecificResetFilterProtocolGuid
* gEdkiiPlatformSpecificResetHandlerProtocolGuid

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.

This hole will cause page fault randomly. The root cause is that Guard
page, which is just freed back to page pool but not yet cleared not-
present attribute, will be allocated right away by internal function
CoreFreeMemoryMapStack(). The solution to this issue is to clear the
not-present attribute for freed Guard page before doing any free
operation, instead of after those operation.
The reason we didn't do this before is due to the fact that manipulating
page attributes might cause memory allocation action which would cause a
dead lock inside a memory allocation/free operation. So we always set or
unset Guard page outside the memory lock. After a thorough analysis, we
believe clearing a Guard page will not cause memory allocation because
memory we're to manipulate was already manipulated before for sure.
Therefore there should be no memory allocation occurring in this
situation.
Since we cleared Guard page not-present attribute before freeing instead
of after freeing, the debug code to clear freed memory can now be restored
to its original way (aka no checking and bypassing Guard page).

may be slightly larger. I.e. each scan line will have some "pixels"
that are not visible on the screen but consume space in the frame
buffer.
If the graphics output protocol correctly initializes
HorizontalResolution to 1366 and PixelsPerScanLine to 1376. As a

If setting HorizontalResolution to 1376 instead, the output is fine

Today's implementation prints nothing when the format string cannot
fit in the report status extended data buffer.
It confuses user.
The patch changes to print partial message by truncating the format
string when it's too long.
The missing enhancement is the extended data buffer only reserves 96
bytes for the var-args. When the format string is not very long but
contains 13 %lx or %p, the var-args buffer is too small. Today's
implementation prints nothing for this case.
This patch doesn't change such behavior.

Three issues addressed here:
a. Make NX memory protection and heap guard to be compatible
The solution is to check PcdDxeNxMemoryProtectionPolicy in Heap Guard to
see if the free memory should be set to NX, and set the Guard page to NX
before it's freed back to memory pool. This can solve the issue which NX
setting would be overwritten by Heap Guard feature in certain
configuration.
b. Returned pool address was not 8-byte aligned sometimes
This happened only when BIT7 is not set in PcdHeapGuardPropertyMask. Since
8-byte alignment is UEFI spec required, letting allocated pool adjacent to
tail guard page cannot be guaranteed.
c. NULL address handling due to allocation failure
When allocation failure, normally a NULL will be returned. But Heap Guard
code will still try to adjust the starting address of it, which will cause
a non-NULL pointer returned.

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.
