From 31aa4524dad1a55ecf1311ae3c89b03b1e0f43ae Mon Sep 17 00:00:00 2001
From: Dave Chapman <dave@dchapman.com>

Subject: Mainly internal changes to create a struct ipod_t instead of passing
 lots of parameters to all the functions.  Also adds (untested) 3G support,
 plus a --write-firmware-bin option (requested by IPL people to write a kernel
 directly to the firmware partition).
