Wouldn't invalidate_dcache_range() be enough here ? You don't care about the data in the newly allocated area at this point I guess -- either you fill them in and then flush, for DMA from CPU to device OR you receive data from device to CPU and then you invalidate this buffer again.
Thanks a lot for your suggestion. I added invalidate_dcache_range() which will check if the initda instruction is supported by the nios2 cpu.
Ah, thanks!
