To consume FIT table for Microcode update,
UefiCpuPkg/Feature/Capsule/MicrocodeUpdateDxe
needs to be updated to consume
IntelSiliconPkg/Include/IndustryStandard/FirmwareInterfaceTable.h,
but UefiCpuPkg could not depend on IntelSiliconPkg.
Since the Microcode update feature is specific to Intel,
we can first move the Microcode update feature code from
UefiCpuPkg to IntelSiliconPkg [first step], then update
the code to consume FIT table [second step].
This patch series is for the first step.
Note: No any code change in this patch, just move.
Next patch will update MicrocodeUpdate to build with the package.

After commit 91cc526b15 "MdeModulePkg/SerialDxe: Fix not able to change
serial attributes", serial is initialized using the reset method that
will call SetAttributes.
However, SetAttributes may return EFI_INVALID_PARAMETER when a driver
does not support some parameters. This will be propagated by the reset
function and lead to UEFI failing to get the console setup.
For instance, this is the case when using the Xen console driver.
Fix it by introspecting the result and return EFI_SUCCESS when the
SetAttributes report an invalid parameter (i.e EFI_INVALID_PARAMETER).

SerialSetAttributes is meant to match the behavior of the function
EFI_SERIAL_IO_PROTOCOL.SetAttributes() in the UEFI spec (v2.7). This
means the function can only return:
- EFI_SUCCESS
- EFI_INVALID_PARAMETER
- EFI_DEVICE_ERROR
However the function SerialPortSetAttributes may also validly return
EFI_UNSUPPORTED. For instance this is the case of the Xen Console
driver.
EFI_UNSUPPORTED could be also interpreted as "One or more of the attributes
has an unsupported value". So return EFI_INVALID_PARAMETER in that case.
Lastly, to prevent another return slipping in the future, all the errors
but EFI_INVALID_PARAMETER and EFI_UNSUPPORTED will return
EFI_DEVICE_ERROR.

DXE performance gauge record access functions might be reentered since
we are supporting something like USB hot-plug, which is a timer event
where gBS->ConnectController might be called and then PERF will be
called in CoreConnectSingleController.
When StartGaugeEx is being reentered, not only the gauge record might
be overwritten, more serious situation will be caused if gauge data
buffer reallocation procedure is interrupted, between line 180 and 187
in DxeCorePerformanceLib.c specifically. There, mMaxGaugeRecords will
be doubled twice (denoted as 4X), but mGaugeData only points to a
buffer of size 2X, which will probably cause the following 2X memory
to be overflowed when gauge records are increased.
So we add EFI lock with TPL_NOTIFY in StartGaugeEx/EndGaugeEx/GetGaugeEx
to avoid memory overflow and gauge data corruption.

The previous change in ShellLib: "commit

* ShellPkg/ShellLib: Constructor doesn't depend on ShellParameters"
resolved the issue when loading dynamic command driver from Shell
environment.
But when dynamic command driver is built into FV and started during
boot, the driver still fails to start because Shell protocol doesn't
exist at that time.
The patch changes ShellLib to:
1. Do not look for Shell and ShellParameters protocol when they are
non-NULL in ShellLibConstructorWorker();
The two protocols are assumed to be set by DynamicCommand.Handler.
When ShellInitialize() is called in DynamicCommand.Handler, this
change can prevent the two protocols to be changed to NULL by
the locating logic.
2. Do not reset the Shell and ShellParameters protocol to NULL in
ShellLibDestructor() when CloseProtocol() fails;
Dynamic command driver needs to set the PcdShellLibAutoInitialize
to FALSE in order to skip the constructor.
Current logic calls ShellLibDestructor() when the PCD is FALSE when
ShellInitialize() is called. The change prevent the two protocols
to be changed to NULL.
The two changes don't impact existing usage case so they are backward
compatible.

This means that SetBootOrderFromQemu() will preserve all UEFI boot options
matched by any given OFW devpath, such as PXEv4, HTTPv4, PXEv6 and HTTPv6
boot options for the same NIC. Currently we stop the matching / appending
for the OFW devpath coming from the outer loop whenever we find the first
UEFI boot option match in the inner loop.
(The previous patch was about multiple OFW devpaths matching a single UEFI
boot option (which should never happen). This patch is about a single OFW
devpath matching multiple UEFI boot options. With the "break" statement
removed here, the small optimization from the last patch becomes a bit
more relevant, because now the inner loop always counts up to
ActiveCount.)

The SetBootOrderFromQemu() function implements a nested loop where
- the outer loop iterates over all OpenFirmware (OFW) device paths in the
QEMU boot order, and translates each to a UEFI device path prefix;
- the inner loop matches the current (translated) prefix against all
active UEFI boot options in turn;
- if the UEFI boot option is matched by the translated prefix, the UEFI
boot option is appended to the "new" UEFI boot order, and marked as
"has been appended".
This patch adds a micro-optimization where already matched / appended UEFI
boot options are skipped in the inner loop. This is not a functional
change. A functional change would be if, as a consequence of the patch,
some UEFI boot options would no longer be *doubly* matched.
For a UEFI boot option to be matched by two translated prefixes, one of
those prefixes would have to be a (proper, or equal) prefix of the other
prefix. The PCI and MMIO OFW translation routines output such only in the
following cases:
- When the original OFW device paths are prefixes of each other. This is
not possible from the QEMU side. (Only leaf devices are bootable.)
- When the translation rules in the routines are incomplete, and don't
look at the OFW device paths for sufficient length (i.e., at nodes where
they would already differ, and the difference would show up in the
translation output).
This would be a shortcoming of the translation routines and should be
fixed in TranslatePciOfwNodes() and TranslateMmioOfwNodes(), whenever
identified.
Even in the second case, this patch would replace the double appending of
a single UEFI boot option (matched by two different OFW device paths) with
a correct, or cross-, matching of two different UEFI boot options. Again,
this is not expected, but arguably it would be more correct than duplicate
boot option appending, should it occur due to any (unexpected, unknown)
lack of detail in the translation routines.
