Subject: 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 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.
