Zhang, Chao B 4073f85d4a MdeModulePkg: Deprecate EFI_VARIABLE_AUTHENTICATED_WRITE_ACCESS
Mark EFI_VARIABLE_AUTHENTICATED_WRITE_ACCESS as deprecated.
1. Make SetVariable/QueryVariableInfo return EFI_UNSUPPORTED with this
   attribute
2. No change to GetVariable/GetNextVariableName
Also update several function descriptors accordingly

Ruiyu Ni 618ef6f9ba MdeModulePkg/Bds: Remove assertion in BmCharToUint
BmCharToUint() could be called using external data and it
already contains logic to return -1 when data is invalid,
so removing unnecessary assertion to avoid system hang.

Hao Wu 16f6922709 MdeModulePkg: Refine casting expression result to bigger size
There are cases that the operands of an expression are all with rank less
than UINT64/INT64 and the result of the expression is explicitly cast to
UINT64/INT64 to fit the target size.

An example will be:
UINT32 a,b;
// a and b can be any unsigned int type with rank less than UINT64, like
// UINT8, UINT16, etc.
UINT64 c;
c = (UINT64) (a + b);

Some static code checkers may warn that the expression result might
overflow within the rank of "int" (integer promotions) and the result is
then cast to a bigger size.

The commit refines codes by the following rules:
1). When the expression is possible to overflow the range of unsigned int/
int:
c = (UINT64)a + b;

2). When the expression will not overflow within the rank of "int", remove
the explicit type casts:
c = a + b;

3). When the expression will be cast to pointer of possible greater size:
UINT32 a,b;
VOID *c;
c = (VOID *)(UINTN)(a + b); --> c = (VOID *)((UINTN)a + b);

4). When one side of a comparison expression contains only operands with
rank less than UINT32:
UINT8 a;
UINT16 b;
UINTN c;
if ((UINTN)(a + b) > c) {...} --> if (((UINT32)a + b) > c) {...}

For rule 4), if we remove the 'UINTN' type cast like:
if (a + b > c) {...}
The VS compiler will complain with warning C4018 (signed/unsigned
mismatch, level 3 warning) due to promoting 'a + b' to type 'int'.

Ruiyu Ni 0dc3359ac6 MdeModulePkg/Bds: Fix a bug that may causes S4 fails to resume
When firmware boots to UiApp, the memory type information settings
are saved to NV storage and the settings in HOB are changed as well.
Because UiApp is an APPLICATION type of boot option, system doesn't
reset when settings change.
But when user selects OS to boot in UiApp, because the settings in HOB
was updated when booting to UiApp, the BDS doesn't think the settings
change, expected reset doesn't happen.

The patch fixes this issue to not update the settings in HOB.

Ruiyu Ni 3a986a353d MdeModulePkg/Bds: MemoryTypeInformation excludes boot option mem use
The patch re-orders the sequences by putting updating memory type
information before loading the boot option so that the reserved
memory usage by HTTP RAM disk boot can be excluded by the memory
type information updating.

Sunny Wang fb5848c588 MdeModulePkg/UefiBootManagerLib: Fix data in MemoryTypeInformation
After booting a large-size ISO RAM disk (HTTP boot option pointing to
a ISO file) and reboot system, system will possibly run into the
following ASSERT because the BDS core code doesn't consider the
case that Memory page management (Page.c) would possibly NOT update
current memory usage statistics(CurrentMemoryTypeInformation) if
system allocates a memory buffer with a large number of pages.
ASSERT [DxeCore] u:\MdeModulePkg\Core\Dxe\Gcd\Gcd.c(2273):
Length >= MinimalMemorySizeNeeded

The BDS code block for skipping counting reserved memory occupied
by RAM Disk didn't consider the Memory page management's behavior
mentioned above, which caused that the
CurrentMemoryTypeInformation[Index1].NumberOfPages will be updated
to a "very big value" because RamDiskSizeInPages is bigger than
CurrentMemoryTypeInformation[Index1].NumberOfPages. For example,
NumberOfPages is 0x9000 (current use) and RamDiskSizeInPages is
0xC0000 (ISO image size). The result will become a very big value
0xFFF49000.

Therefore, we need to add a check to prevent BDS core code updating
wrong data (very big value) to MemoryTypeInformation variable. This
code change is a improvement for fixing this issue for most cases.
There is still a corner case even when the memory bins don't include
the RAM disk memory, the memory used by all other modules exceeds
RamDiskSizeInPages. Ray will send the other patch to fix this corner
case.
