I am currently working on a ppc(mpc8349) platform.
I modified BR3 and OR3 to enable LCS3 when I'm trying to access a specific address on the local bus in a GPCM mode.
The problem is that i don't know how to access my device on the local bus.
I know that i have to change the physical address to virtual address, but what are those functions . . .
do we have dma function ?should i use virt_to_bus(...) or bus_to_virt(...) ?
some help could be very appreciated
Thank you all
