    2 # AR724X -- Kernel configuration file for FreeBSD/MIPS for Atheros 724x systems
    3 #
    4 # This includes all the common drivers for the AR724x boards.
    5 # Since the AR724x boards tend to have minimal flash (sometimes 4MB!),
    6 # the majority of the kernel framework will be built as modules.
