[commit] r728 - in trunk/openbios-devel: arch/sparc32 arch/sparc64 arch/x86 forth/debugging

[repository service]

Author: mcayland
Date: Fri Apr  2 16:03:38 2010
New Revision: 728
URL: http://tracker.coreboot.org/trac/openbios/changeset/728

Log:
Now that we have a C version of go available, rework client.fs so that it will automatically detect if a platform has execution 
capability based upon the existence of the lower level (go) word. Also add standard ELF image support to (go) for SPARC32, 
SPARC64 and x86.
