[commit] r699 - in trunk/openbios-devel/include: libopenbios openbios - OpenBIOS

14 Mar 2010

Author: mcayland
Date: Sun Mar 14 22:02:58 2010
New Revision: 699
URL: http://tracker.coreboot.org/trac/openbios/changeset/699
Log:
Only one file remains - asm.m4. I have absolutely no idea what this file is supposed to do (since it doesn't seem to be called) 
so I'll move in into include/libopenbios for the time being. Anyone know what this file is used for?
