/* July 29, 2004
*
* This is a hacked replacement for the 'addpattern' utility used to
* create wrt54g .bin firmware files. It isn't pretty, but it does
* the job for me.
*
* Extensions:
* -v allows setting the version string on the command line.
* -{0|1} sets the (currently ignored) hw_ver flag in the header
* to 0 or 1 respectively.
*/
/* January 12, 2005
*
* Modified by rodent at rodent dot za dot net
* Support added for the new WRT54G v2.2 and WRT54GS v1.1 "flags"
* Without the flags set to 0x7, the above units will refuse to flash.
*
* Extensions:
* -{0|1|2} sets {0|1} sets hw_ver flag to 0/1. {2} sets hw_ver to 1
* and adds the new hardware "flags" for the v2.2/v1.1 units
*/
/* January 1, 2007
*
* Modified by juan.i.gonzalez at subdown dot net
* Support added for the AG241v2 and similar
*
* Extensions:
* -r #.# adds revision hardware flags. AG241v2 and similar.
*
* AG241V2 firmware sets the hw_ver to 0x44.
*
* Example: -r 2.0
*
* Convert 2.0 to 20 to be an integer, and add 0x30 to skip special ASCII
* #define HW_Version ((HW_REV * 10) + 0x30) -> from cyutils.h
