21 * This is a hacked replacement for the 'addpattern' utility used to
22 * create wrt54g .bin firmware files. It isn't pretty, but it does
26 * -v allows setting the version string on the command line.
27 * -{0|1} sets the (currently ignored) hw_ver flag in the header
28 * to 0 or 1 respectively.
33 * Modified by rodent at rodent dot za dot net
34 * Support added for the new WRT54G v2.2 and WRT54GS v1.1 "flags"
35 * Without the flags set to 0x7, the above units will refuse to flash.
38 * -{0|1|2} sets {0|1} sets hw_ver flag to 0/1. {2} sets hw_ver to 1
39 * and adds the new hardware "flags" for the v2.2/v1.1 units
