forked from len0rd/rockbox
I noticed a few mistakes in the old driver code and it was in need of an overhaul anyway... I decided to scale things back, simplify the code and remove most of the debug menus, netting a nice code size savings. One new feature is an advanced debug menu which is accessible by recompiling the code with AXP_EXTRA_DEBUG. It adds quite a bit of code size and isn't useful other than for development so it must be manually enabled by editing the source. Change-Id: I30e17c1194c14823decd726a574ed14451d4cb2d
