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'.

to context. But BIT0 is used without Slot when UfsWaitMemSet ()
is invoked.

According to UFS Host Controller Spec(JESD223), the bits 1:0 of this
DataByteCount field shall be 11b to indicate Dword granularity.
But the size of UFS Request Sense Data Response defined in UFS Spec
(JESD220C) is 18 which is not Dword aligned, we would have to round
down to the multiple of 4 to fill the DBC field to avoid bring issue
on some UFS HCs.

This commit will raise the Tpl to TPL_NOTIFY when adding non-blocking SCSI
I/O requests to the asynchronous task list.
This commit will also raise the Tpl of asynchronous task polling timer to
TPL_NOTIFY.
These changes are made to match the behavior in ScsiDiskDxe driver.

In function SignalCallerEvent(), 'Private' and 'TransReq' are dereferenced
before NULL checking.
Since the function assumes that both 'Private' and 'TransReq' passed in
are not NULL pointer, this commit will add an ASSERT to make sure the
above assumption is satisfied.

Previously, UfsPassThruPassThru function does not handle the 'Event'
parameter and blocking read/write operations are always executed.
This commit enables non-blocking read/write feature for UFS devices.

GLOBAL_REMOVE_IF_UNREFERENCED means __declspec(selectany) for MS tool
chain IA32/X64 build.
According to MSDN, "selectany" would tell the compiler that the declared
global data item (variable or object) is a pick-any COMDAT (a packaged
function). At link time, if multiple definitions of a COMDAT are seen,
the linker picks one and discards the rest.
So we have to remove GLOBAL_REMOVE_IF_UNREFERENCED key word from two global
variable's extern definitions of .h file as we have used this keyword in
.c file, otherwise the MS tool chain would pick the definitions in .h file
and treat it as uninitialized data to generate full-0 content for these two
global variables.
