[alsa-devel] submitting a patch against the ALSA repos

I have submitted my patch against the 2.6.21 kernel tree but I dare say I need to actually submit it against the alsa repos.

I have a few questions:

1. Which set of sources do I patch - I assume alsa-driver - is that right?

2. How do I patch the firmware repo? As it is a binary I assume it is by some means other than patch(1)

3. This is a new architecture - there are no other SuperH drivers in alsa (afaik) - how do I add a new architecture? My memory is that when I tried this a year ago it was a bit of a nightmare.
