This Patch add the support to set UFS clock frequency.
- Added the function to read or write specified attribute of a UFS device
- Shifted function which switch the link power mode and gear after ref_clock setting
because if an unsuported clock frequency being set, it won't be able to overwrite
the corrupted UFS attributes.

Whenever EV_EFI_VARIABLE_DRIVER_CONFIG is specified as TPM event type,
the data that accompanies it is expected to be an UEFI variable in the
appropriate format
This change fixes an erroneously typed TPM event so that the tpm2_eventlog
command works in Linux

On platforms where only serial console input is enabled, enabling
source debug will lead to an infinite loop in ConsoleRead(). Newer

Currently, loading an ELF image will relocate the image (to its
preferred load address) only if there is at least one ELF segment
that is not completely contained in the file loaded (i.e. the memory
segment size is larger than the size inside the file. This behavior
is generally triggered by the segment that contains the .bss section).
Consequently, images that contain initialized data only (e.g. QNX IFS
files) don't get relocated, and will usually crash when jumping to the
image entry point.
This change checks whether the ELF image is already loaded at the
preferred address, and forces image relocation if not.

This patch fixes 2 issues related to symbolic links:
1. when "fs ls" a directory, symbolic links are not shown.
It is because Ext2fsLs() only shows regular files and directories.
2. when "fs ls <symbolic_link>" the output is incorrect.
It is because File->FileNamePtr points to a local variable,
"NameBuf" in Ext2fsOpen(), if the file is a symbolic link
This patch replaces File->FileNamePtr with FileNameBuf.
It slightly increases Ext2fsLs/Ext2fsOpen/SearchDirectory time,
because of the use of strcpy and strcat.
Test method:
1. create a regular file, "a", in directory "x"
2. create a symbolic link file, "b", pointing to "a".
3. under the shell of OSLoader,
"fs ls x"
- expected result: a, b (symbolic link)
"fs ls x/a"
- expected result: a and its file size is shown
"fs ls x/b"
- expected result: b -> a, and the file size of a is shown

This patch fixes an issue that SBL fails to load a file in Ext4 partition,
when
1. the ext4 partition uses Extent
2. the inode's first extent block is an internal node
3. the node has only one entry (i.e., eh_entries = 1)
Under the above conditions, the data block may point to the child of
first ei_block when accessing the data within the range of child node.
Test method:
1. Install Ubuntu 20.04.5 LTS/(min install) in an eMMC disk
Note: this issue is only reproducible when loading a file
satisfying all conditions mentioned above (i.e., eh_entries = 1).
So far, the /boot/initrd.img after installing Ubuntu in an eMMC
(where part table: 500MB(FAT), 20GB (EXT4), 4GB (Swap)) satisfies
the conditions. However, for some reasons, when using USB SATA disk,
it will not generate a /boot/initr.rd meeting the conditions.
2. Boot to OSLoader
3. "fs init 2:0 0 1" the eMMC disk (assume the HW:SW-part is 0 1)
4. "fs load boot/initrd.img"
Expected result:
1. With this patch: successfully load the file.
2. Without this patch: ASSERT [OsLoader] ..

In the Ubuntu ISO image, it has 0xF8 partition entries.
The partition library could not work as expected since
it expects the partition entries are no more than 128.
Potentially it could have more partition entries, so just
remove the check.

This patch fixes an invalid memory access issue caused by
the fs->Ext2FsGDSize is smaller than the size of EXT2GD.
The EXT2GD is a 64-byte structure, but fs->Ext2FsGDSize is not always 32.
Before this patch, Ext2fsOpen() allocates a smaller memory than expected:
i.e., Ext2FsGrpDes = AllocatePool (Ext2FsGDSize * Ext2FsNumCylinder);
When ReadGDBlock() loads data (E2FS_CGLOAD) into fs->Ext2FsGrpDes,
it possibly accesses mem out of the allocated Ext2FsGrpDes space.
This patch loads each element into fs->Ext2FsGrpDes.
This patch also
1. prints informative messages when OS Loader fails to load Linux files.
2. increase EHL's PLD_HEAP_SIZE (since the size of initrd in Ubuntu LiveCD
is over 130MB)
Test method:
1. create a huge EXT FS (says, at least 36GB)
2. In the fs, place the following file/dir:
a: non-empty file
b: dir
b/c: non-empty file
3. boot with SBL OS Loader and enter Shell.
4. execute "fs init <...skip...>" to init the fs
5. execute "fs ls"
6. execute "fs ls b/c"
7. execute "fs load a"
8. execute "fs load b/c"
Verify:
1. 10MB/10GB/100GB/200GB EXT2/EXT3/EXT4 FS
2. EHL CRB
