And I seem to recall there's more SATA chipset documentation than Jeff
Garzik has time to implement support for.
I seriously doubt you can come up with even a single concrete example here.
Not trying to slight Jeff here in any way, but I thought I'd point out
one driver-less SATA chip that seems to have docs available.
When looking for a sata controller I came across several inexpensive
ones based on an Initio chipset, and at first glance it seems that they
have docs out there*: http://www.initio.com/products/sata.htm
but no drivers yet. Just in case anyone is interested :)
The driver is in libata-dev.git#upstream and queued for 2.6.21.

Woo! that was fast. Ok I stand corrected. :)
Be warned. The driver is marked HIGHLY EXPERIMENTAL and it seem to work
only on my machine. Seems to have some problem with LBA48 support.
The datasheet initio posted on the website just contains register
descriptions, which is much better than nothing but I still had to do a
LOT of trial-and-error to make that thing quasi-working. I've tried to
contact them in many ways but couldn't get any response. I'll probably
get back to it in a few weeks.
I can write ATA drivers for most hardware in a few days given 1.
actually useful datasheet 2. hardware at hand 3. an ENGINEER to talk to
when I get stuck. So, sign me up.
It will be nice to have some central web site / wiki / whatever to
monitor progress, arbitrate jobs, provides link to relevant info and
people (probably some of them being open-by-request) and possibly
provide links to bugzilla entries.
