For 'addr' we may try to use 4 bytes instead of the current 32 ones but lets
fix the regression first.
Alas, TX4939 requeires 8-byte DMA address (and byte count) alignment.
Another semi-compatible SFF-8038 implementation...

saying something like: hello, I'm a xy device and I can do z bytes dma
alignment, otherwise I get cranky and don't work anymore :)
I didn't get it -- TX4939 is IDE host controller and I can't imagine
how an ATAPI device could care about the buffer address alignment on the
host side...
