commit c4d202a8da739ec8e21ad68b155f498f631ec0dd

    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?
    echo, expr, 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.
