If you use OpenBSD driver as base, you may have to change a lot of
DMA related code due to bus_dma(9) differences. After converting
DMA code, other parts would be straightforward to make it work on
FreeBSD. Sun released Cassini documentation with sanitization. The
data sheet lacks errata information and hardware internals but it
still has a lot of useful information.
