commit c68e1cb7b9d70441e5712b265901256c7cc1a5b4 Author: zbao fishbaozi@gmail.com Date: Tue Aug 21 19:24:02 2012 +0800
AMD Hudson: Move the combining firmware from Python to sh.
Maybe sooner or later python is not a default tools to build coreboot. Most of the work is done by awk now. GNU extension of gawk is not used, isn't? printf, cat, awk, test, mv are the external tools. If XHCI, IMC or GEC firmware is not available and not defined, this script can skip integrating them.
