Nice job Pierre,

On my side, i am still trying to get Bluetooth working.
Brf6150 device is for sure plugged on pxa BT UART (that is to say ttyS1)
 
I am still figuring out what should be done in order to power ON and
reset the device ...
 
On hx4700 (which has also a brf6150), power ON is done by setting bit 5
of egpio register to 1, and reset of the device is done using GPIO 106.
Bad luck, this does NOT work on axim ....

So i am playing with Haret to look at GPIO's behavior when
enabling/disabling Bluetooth... GPIO 22 seems to be consistently set to
1 each time bluetooth is ON (and reset to 0 if turned OFF)

Another matter : i am NOT sure that EGPIO is located at PXA Chip selects
5 / offset 0 .....

Once brf6150 is reset and in idle, just "modprobe hci_uart" and
"hciattach /dev/ttyS1 texas 115200" should do the rest ....

Any help is welcome !
Nicolas.
