For pointer subtraction, the result is of type "ptrdiff_t". According to
the C11 standard (Committee Draft - April 12, 2011):
"When two pointers are subtracted, both shall point to elements of the
same array object, or one past the last element of the array object; the
result is the difference of the subscripts of the two array elements. The
size of the result is implementation-defined, and its type (a signed
integer type) is ptrdiff_t defined in the <stddef.h> header. If the result
is not representable in an object of that type, the behavior is
undefined."
In our codes, there are cases that the pointer subtraction is not
performed by pointers to elements of the same array object. This might
lead to potential issues, since the behavior is undefined according to C11
standard.
Also, since the size of type "ptrdiff_t" is implementation-defined. Some
static code checkers may warn that the pointer subtraction might underflow
first and then being cast to a bigger size. For example:
UINT8 *Ptr1, *Ptr2;
UINTN PtrDiff;
...
PtrDiff = (UINTN) (Ptr1 - Ptr2);
The commit will refine the pointer subtraction expressions by casting each
pointer to UINTN first and then perform the subtraction:
PtrDiff = (UINTN) Ptr1 - (UINTN) Ptr2;

Non-discoverable devices need to be registered explicitly by the platform.
Introduce a helper library that takes care of this.
This implementation currently only supports registering devices that are
covered by one or more MMIO resources. The underlying protocol allows for
more flexibility than that, but this is currently sufficient for the use
cases that we know about.

The classful addressing (IP class A/B/C) has been deprecated according to
RFC4632. This patch updates the NetLib NetGetIpClass() and NetIp4IsUnicast()
accordingly.
NetGetIpClass()
The function is kept for compatibility, while the caller of this function
could only check the returned value against with IP4_ADDR_CLASSD (multicast)
or IP4_ADDR_CLASSE (reserved) now. The function has been updated to note this.
NetIp4IsUnicast()
The NetMask becomes a required parameter to check the unicast address.

2. Change BootLogoLib to consume the new PlatformLogo protocol.
3. Change BootLogoEnableLogo() to only use images returned from

This is a enhancement to support the case when platform firmware
doesn't support Boot Manager Menu. For now, if BootManagerMenu FFS
can not be retrieved from FV, BDS core code will still register a
boot option for it. Then, this non-functional boot option will
still be booted by user's request (like HotKey or Exit from shell)
to cause additional boot time and error status code reported.
Therefore, it would be good to skip BootManagerMenu boot option
registration and then return error status and Invalid BootOption
data for this case so that the BootManagerBoot() or other consumers
can directly return without doing anything.

The BootLogoUpdateProgress() function uses the
EFI_GRAPHICS_OUTPUT_BLT_PIXEL type in its parameter list, but the protocol
header that defines this type is not included. This breaks dependent C
source files that don't otherwise include the GraphicsOutput protocol
header. Supply the necessary include directive.
(Similarly, BootLogoEnableLogo() uses
EDKII_PLATFORM_LOGO_DISPLAY_ATTRIBUTE in its parameter list. For that
however, the PlatformLogo protocol header is included already.)

Some platform doesn't require PciBus driver to assign resource
to PCI devices which causes PciRootBridgeIo.Configuration() cannot
return correct resource information to caller.
When resource assignment by PciBus is not mandatory, only light
version of PCI bus enumeration is performed, which only collects
the device resource consumption and publishes the PciIo instance.
The corresponding logic is in PciEnumeratorLight() in PciBus driver.
But PciEnumeratorLight() still depends on
PciRootBridgeIo.Configuration() returns the starting bus number in
order to search down to find all PCI devices under the root bridge.
When ResourceAssigned in PCI_ROOT_BRIDGE returned by
PciHostBridgeGetRootBridges() is TRUE, PciHostBridge driver treats
the Bus/Io/Mem/MemAbove4G/PMem/PMemAbove4G as the resource that are
*actually assigned* to the root bridge, instead of the resource that
*can be assigned* to the root bridge.
So that PciRootBridgeIo.Configuration() can return the correct
information.

The user is not expected to do a AsciiStrLen anymore, and is not

using AsciiStrLen on such a string can provide truncated lengths.

#define IP6_PREFIX_MAX 128
we will use these two macros to check the max mask/prefix length,
instead of
#define IP4_MASK_NUM 33
#define IP6_PREFIX_NUM 129
which means a valid number.
This will make the code readability and maintainability.
