To improve performance 9b18845a4b4cd1d2cf004cbc1cadf8a93ccb37ea
changed the code which read from physical MMIO address to read
from memory cache, but it missed some places that could be updated
the same away for performance optimization.
The patch updates these places as supplementary.
I found them when updating code for

Merge EmuVariable and Real variable driver.
Add macro NV_STORAGE_VARIABLE_BASE.
Not get NV PCD in VariableWriteServiceInitialize, but in
FtwNotificationEvent/SmmFtwNotificationEvent, then
VariableWriteServiceInitialize could be not aware the NV
storage is real or emulated.
This patch prepares for adding emulated variable NV mode
support in VariableRuntimeDxe.

Merge EmuVariable and Real variable driver.
Abstract VariableWriteServiceInitializeDxe/Smm from
FtwNotificationEvent/SmmFtwNotificationEvent, then
VariableWriteServiceInitializeDxe/Smm could be not aware
the NV storage is real or emulated.
This patch prepares for adding emulated variable NV mode
support in VariableRuntimeDxe.

Merge EmuVariable and Real variable driver.
CacheOffset could be removed in UpdateVariable() after
//
// update the memory copy of Flash region.
//
CopyMem (
(UINT8 *)mNvVariableCache + CacheOffset,
(UINT8 *)NextVariable, VarSize
);
is moved to be before mVariableModuleGlobal->NonVolatileLastVariableOffset
value is updated, like right before
mVariableModuleGlobal->NonVolatileLastVariableOffset +=
HEADER_ALIGN (VarSize);
Except for the movement above, the patch also capitalizes the first
character of "update the memory copy of Flash region".
This patch prepares for adding emulated variable NV mode
support in VariableRuntimeDxe.

Merge EmuVariable and Real variable driver.
Add emulated variable NV mode support in real variable driver.
Platform can configure PcdEmuVariableNvModeEnable statically
(build time) or dynamically (boot time) to support emulated
variable NV mode.
If PcdEmuVariableNvModeEnable is configured to dynamic, its
value should be set before Variable driver starts to work,
otherwise default value will take effect.
Then EmuVariableRuntimeDxe could be removed, the removal of
EmuVariableRuntimeDxe will be done after platforms are migrated
to use the merged variable driver.

>
> REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1323
> Merge EmuVariable and Real variable driver.
>
> Add emulated variable NV mode support in real variable driver.
> Platform can configure PcdEmuVariableNvModeEnable statically
> (build time) or dynamically (boot time) to support emulated
> variable NV mode.
>
> If PcdEmuVariableNvModeEnable is configured to dynamic, its
> value should be set before Variable driver starts to work,
> otherwise default value will take effect.
>
> Then EmuVariableRuntimeDxe could be removed, the removal of
> EmuVariableRuntimeDxe will be done after platforms are migrated
> to use the merged variable driver.

Merge EmuVariable and Real variable driver.
The real variable driver has been updated to support emulated
variable NV mode and the EmuVariableRuntimeDxe will be removed
later, so use merged variable driver for emulated NV mode.

This patch is not related directly to
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1323
Merge EmuVariable and Real variable driver.
It just makes ArmVirtXen be aligned with ArmVirtQemuXXX to
link VarCheckUefiLib NULL class library instance.

Merge EmuVariable and Real variable driver.
The real variable driver has been updated to support emulated
variable NV mode and the EmuVariableRuntimeDxe will be removed
later, so use merged variable driver for emulated NV mode.

The real variable driver has been updated to support emulated
variable NV mode and the EmuVariableRuntimeDxe will be removed
later, so use merged variable driver for emulated NV mode.

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1323
Merge EmuVariable and Real variable driver.
The real variable driver has been updated to support emulated
variable NV mode.
This patch removes EmuVariableRuntimeDxe after platforms are
migrated to use the merged variable driver.

- This function supports both ISO 639-2 and RFC 4646 language codes, but language
- code types may not be mixed in a single call to this function. This function
- supports a variable argument list that allows the caller to pass in a prioritized
- list of language codes to test against all the language codes in SupportedLanguages.
-
- If SupportedLanguages is NULL, then ASSERT().
-
- @param[in] SupportedLanguages A pointer to a Null-terminated ASCII string that
- contains a set of language codes in the format
- specified by Iso639Language.
- @param[in] Iso639Language If not zero, then all language codes are assumed to be
- in ISO 639-2 format. If zero, then all language
- codes are assumed to be in RFC 4646 language format
- @param[in] ... A variable argument list that contains pointers to
- Null-terminated ASCII strings that contain one or more
- language codes in the format specified by Iso639Language.
- The first language code from each of these language
- code lists is used to determine if it is an exact or
- close match to any of the language codes in
- SupportedLanguages. Close matches only apply to RFC 4646
- language codes, and the matching algorithm from RFC 4647
- is used to determine if a close match is present. If
- an exact or close match is found, then the matching
- language code from SupportedLanguages is returned. If
- no matches are found, then the next variable argument
- parameter is evaluated. The variable argument list
- is terminated by a NULL.
-
- @retval NULL The best matching language could not be found in SupportedLanguages.
- @retval NULL There are not enough resources available to return the best matching
- language.
- @retval Other A pointer to a Null-terminated ASCII string that is the best matching
- language in SupportedLanguages.
