I'm working with the a linux 2.6.20.9 with patches from Sylvain's tree. I've been looking the Den'x 2.5.xx SPI support and it seems that it is done through GPIOs. I'd like a native SPI implementation, using the hardware of the MPC5200, because of the performance issue of using a GPIO, because I'd like to use it at full speed.
Is it done really with GPIOs? If so, is there any other implementation? If it is possible I'd like it to be for 2.6.x.
