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).

# Timer library implementation
#
# A non-functional instance of the Timer Library that can be used as a template
# for the implementation of a functional timer library instance. This library instance can
# also be used to test build DXE, Runtime, DXE SAL, and DXE SMM modules that require timer
# services as well as EBC modules that require timer services
