Hello everybody a quick question while the subject of SPI driver is in the air
I am trying to reimplement the driver for the SPI based on the driver from David Boppuri and Prashant Patel, and their is a thing I don't understand... for the TX and RX buffer, they use memory they get for m8xx_cpm_hostalloc... why ? Does it have something to do with the MMU ? I would like to avoid doing that, is their a way to use normal ( kernel space) memory ? Thanks Jeremy ** Sent via the linuxppc-embedded mail list.
