[commit] r5386 - in trunk/src: arch/i386/include/arch arch/i386/init cpu/amd/car cpu/x86/car
Author: stepan Date: Fri Apr 9 12:12:18 2010 New Revision: 5386 URL: https://tracker.coreboot.org/trac/coreboot/changeset/5386
Log: thin out romcc epilogue and have it call copy_and_run as all the others do. Make sure copy_and_run is called with the right calling convention. Fix up 2 license headers.
