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). git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@9518 6f19259b-4bc3-4df7-8a09-765794883524
