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).
