I am trying to connect a FPGA/FIFO with my MPC5200b on a phytec PCM 030 board
while running a 2.6.23.1 Linux.
The Linux Kernel source contains an implementation for the Bestcomm API in the
form of a driver for ethernet (fec) and ATA.(situated in the
arch-powerpc/sysdev/bestcomm path) I tried to make use of it but i've run into
some problems.
So i tried to include the API in a module to utilize its functionality but no
luck till now.
Freescale supports the Bestcomm DMA API not on an OS level. So the problem is
adopting this API into a Linux environment, which distinguishes between kernel
space and user space while writing to the appropriate registers.
Further information is very hard to find for such a common task as starting a
DMA transfer.
