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

+/** @file
+  The entry of the embedded BDS. This BDS does not follow the Boot Manager requirements 
+  of the UEFI specification as it is designed to implement an embedded systmes 
+  propriatary boot scheme.
+
+  This template assume a DXE driver produces a SerialIo protocol not using the EFI 
+  driver module and it will attempt to connect a console on top of this.
