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 will fully support PatchCheck.py.
- Remove all trailing whitespace
- Convert LF to CRLF by default
- Update EFI_D_* to DEBUG_*
- Re-enable CRLF check in PatchCheck.py

* Enable DebugAgentLib to support source level debug over serial
By default, source level debug is NOT enabled. ENABLE_SOURCE_DEBUG
needs to be set to 1 in BoardConfig.py of each Platforms.
- self.ENABLE_SOURCE_DEBUG = 1
As an initial drop, there are some limitations on APL platform.
- Stage1A does not include DebugAgentLib due to Stage1A size
limitation(32KB). Further optimization is required.
- DebugAgentLib supports ONLY POSTMEM debugging on APL currently.

This patch implemented USB keyboard library and added it as an
input console device. It can be enabled by setting BIT1 in
self.CONSOLE_IN_DEVICE_MASK in BoardConfig.py. By default, it
will be disabled for performance and size consideration.
Test has been done on APL Leafhill board. USB keyboard can work
in Shell.

Current implementation assumes serial port is the only input console
device supported. But other input console devices can be added later
on. This patch added a ConsoleInLib to abstract the input console
interfaces. It also added PCDs to control enabled input console
devices.
