A better template, with some build scripts, for ArmEbPkg. New libraries are just stubs and need to get filled in. Also debugger scripts are just copies of the BeagleBoard scripts and need to be ported. Compiles with all build 3 build scripts. Cygwin RVCT via build.sh, DOS RVCT via b.bat, and DOS box CodeSourcery GCC via ba.bat.
