If you want to talk ECP straight off, with no negotiation phase, just use
port->ops->ecp_write_block directly.

I'm glad you asked. ;-) The interface needs changing, basically. You can
find documentation on what I'd like it to look like here:


I'd appreciate comments on it. I don't really want to go and make the
changes only to find out that they're not useful. ;-)

It's starting to look much better now. The architecture is separated out
a lot more, and change_mode does something useful.

Please take a look and tell me what you think. The document isn't
finished, but the functions that remain undocumented are guessable (most
already exist and remain unchanged).
