Hi all. Ive managed to proper initialize the bcm2035 on my a780.
No kernel hacking was necessary, i just removed ezx-bt.patch from my series file. The chip works fine without ever touching the 2 gpio lines(for now). The bcm2035 initialization in bluez hciattach is buggy, and i only managed to attach at 115200 and bdaddr of 000000000000, so i wrote my own tool, based on a trace of motorola's dload application. bcm2035-tool can properly set the bdaddr, change baudrare and patch the firmware of the bcm2035 connected to BTUART on EZX phones. You can download it from http://people.openezx.org/wyrm/bcm2035-tool.tgz -- EOF Daniel Ribeiro
