options GXIO_BLUETOOTH_ON_HWUART
options GXIO_DEFAULT_EXPANSION
gxio driver supports several different expansion
boards. Those boards have to be configured either by kernel option or using
boot time parameter. The supported extension boards is system specific.
gxio is available for OMAP based
Overo/DouVero and Pepper as well as for XScale based Gumstix boards. To
setup the expansion board on boot the parameter “expansion”
for OMAP and XScale can be used. Additionally, some XScale systems can
connect two expansion boards. The second board can be configured by the
“busheader” boot parameter. The gxio
driver does not verify validity of both parameters.
For Xscale boards the following drivers are available for the peripherals:
GXIO_BLUETOOTH_ON_HWUARTThe option only affects Xscale PXA250 based Gumstix boards. If set, the serial port HWUART is used to control Bluetooth module. Otherwise no Bluetooth module is configured for PXA250 boards.
GXIO_DEFAULT_EXPANSIONIf configured, the gxio of the
processor is setup for the board. If a boot parameter is used, the boot
value is used instead.
