SPI driver for m8xx

[Jeremy Rosen]

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
