Soemtimes when JTAG based debug is not available, it might be easier
to have Shell access in earlier stage to check lots of platform
settings. Today it is impossible because full Shell has lots of other
dependencies which might not satisfy in early stage. This patch added
a PCD PcdMiniShellEnabled to build a mini Shell with very few
dependencies. This mini Shell can be used in early debug phase for SBL.
To use it, add the following to override the PCD for a specific stage
in BootloaderCorePkg.dsc.
EX:
$(PLATFORM_PACKAGE)/Stage1B/Stage1B.inf {
<PcdsFeatureFlag>
gPlatformCommonLibTokenSpaceGuid.PcdMiniShellEnabled | TRUE
...
}
Then include ShellLib.h in stage C code and add ShellLib in related
stage INF file. If adding it into Stage1A, it needs to be after the
Stage1A banner print out.

This patch removed global variable usages in ShellLib. It is
required when running Shell in early stage from flash. In this
case global variable is read-only. All memory should be allocated
from stack or heap.

This 'fs' shell command can be used for basic file system check.
Usage: fs init [device no.] [hwpart no.] [swpart no.]
fs close
fs info
fs ls [dir or file path]
- 'device no.' is from Platform Device Table.
- all 0s by default if 'fs init' has no parameters
- root dir by default if 'fs ls' has no dir or file path

The 'mm' (formely 'mem') command is being
updated to handle PCI device formatted
addresses and also to support IO device
interfacing. Removing the 'io' command too
since it has been intergrated into the 'mm'
command.

Currently, all shell commands are statically defined in header file.
Add shell command registration API to allow include/exclude shell
commands dynamically.
Later, some debug shell commands will be added according to build
mode or debug mask.
- TBD: Sorting shell commands by name
