Ok. I've looked at your patch a bit more thoroughly,
and it would also be quite easy to do what negotiate
does but without negotiation :-)
Another thing: You've already done the IMHO hard thing,
namely doing ECP on a SPP, but surely we want to
use the hardware ECP mode if available?!
At least in my application it doesn't make sense
to use ECP when the hardware doesn't directly support it.
It may not even make sense to use ECP if DMA is not available,
but I'll have to measure that.

Is the peripherial allowed to do this? I thought address transfers
are only defined in forward mode...
