d8bcb4fac8 fix: [Common] Handle invalid shell command gracefully
Currently an ASSERT is triggered halting the system if the
command length is greater than the argv buffer size. Handle this
error gracefully to avoid system halt.

990e3e81e6 Use LF line endings in the repository
Convert the line endings stored for all text files in the repository to
LF. The majority previously used DOS-style CRLF line endings. Add a
.gitattributes file to enforce this and treat certain extensions as
never being text files.

Update PatchCheck.py to insist on LF line endings rather than CRLF.
However, its other checks fail on this commit due to lots of
pre-existing complaints that it only notices because the line endings
have changed.

Silicon/QemuSocPkg/FspBin/Patches/0001-Build-QEMU-FSP-2.0-binaries.patch
needs to be treated as binary since it contains a mixture of line
endings.

This change has implications depending on the client platform you are
using the repository from:

* Windows

The usual configuration for Git on Windows means that text files will
be checked out to the work tree with DOS-style CRLF line endings. If
that's not the case then you can configure Git to do so for the entire
machine with:

 git config --global core.autocrlf true

or for just the repository with:

 git config core.autocrlf true

Line endings will be normalised to LF when they are committed to the
repository. If you commit a text file with only LF line endings then it
will be converted to CRLF line endings in your work tree.

* Linux, MacOS and other Unices

The usual configuration for Git on such platforms is to check files out
of the repository with LF line endings. This is probably the right thing
for you. In the unlikely even that you are using Git on Unix but editing
or compiling on Windows for some reason then you may need to tweak your
configuration to force the use of CRLF line endings as described above.

* General

970153f09d [Shell] Add memory de-allocation for Shell commands (#662)
SBL Shell allocated memory during the command registeration phase.
However, these memory is not de-allocated after Shell exits. This
patch added code to de-allocate the memory. It also rearranged the
code a little bit so that function declarations are not required
any more.

12f6f62630 Add MiniShell support for debug purpose
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.

2ed3e9c46a Remove Shell global variable usage
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.

bc8a817e59 Reinitialize Shell command list
Since OsLoader will restart from beginning and all memory will be
reclaimed, it is required for Shell library to re-initialize the
global varaibles, for example, command list. Otherwise, the old
memory pointer will be used and cause issues. This patch added the
link list re-initialization in Shell lib.  It fixed #253.

2255bc10b0 Enable basic framebuffer text console output
This patch simplifies the GraphicsLib code and adds an abstraction layer
for printing to a virtual "console," through the familier
ConsoleWrite(buffer, len) style function call.

ConsoleWrite can be configured to output to either the serial port, or
the display framebuffer, or both. This primarily enables the command
shell to be used with a display and keyboard.

bd1ea24cc1 Add ConsoleInLib to abstract console input (#13)
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.
