Fails to compile for me with:
cc1: error: ‘-march=r3000’ requires ‘-mfp32’
using the x86_64 corss gcc 8 from Debian testing.
Either way the config looks like we have all the required bits for
non-coherent dma support. The only guess is that somehow
dma_cache_wback_inv aren't hooked up to the right functions for some
reason, but I can't really think off why.
