Adding support for BeagleBoard.

ArmPkg - Supoprt for ARM specific things that can change as the architecture changes. Plus semihosting JTAG drivers.
EmbeddedPkg - Generic support for an embeddded platform. Including a light weight command line shell.
BeagleBoardPkg - Platform specifics for BeagleBoard. SD Card works, but USB has issues. Looks like a bug in the open source USB stack (Our internal stack works fine).

This function uses policy data from the platform to determine what operating
system or system utility should be loaded and invoked. This function call
also optionally make the use of user input to determine the operating system
or system utility to be loaded and invoked. When the DXE Core has dispatched
all the drivers on the dispatch queue, this function is called. This
function will attempt to connect the boot devices required to load and invoke
the selected operating system or system utility. During this process,
additional firmware volumes may be discovered that may contain addition DXE
drivers that can be dispatched by the DXE Core. If a boot device cannot be
fully connected, this function calls the DXE Service Dispatch() to allow the
DXE drivers from any newly discovered firmware volumes to be dispatched.
Then the boot device connection can be attempted again. If the same boot
device connection operation fails twice in a row, then that boot device has
failed, and should be skipped. This function should never return.
