Message:

BSP now compiles and links with CAVSL board information. This includes
linkcmds updated, simio references removed, and switch to libchip for
serial ports from simio.

Added a MEMORY_MAP file to capture information about the various
addresses on this board.

In addition, many of the beta patches are now included.
