hi,
My friend and I have worked on porting Netbsd on hawkboard, which
has TI's OMAPL-138 SOC. We have been able to boot with the root on the
usb -- getting networking to work is on
our TODO list. This work was based on the 5.1.2 release, and we are
currently working on forward-porting the changes to -current.

We want to submit these changes upstream, and had a couple of doubts
about patch submission.

- the documentation says that any change can be submitted only against
  a PR. Can we open a PR for this patch submission.

- Are the patches to be based on -current, or the latest stable
  release.

- Is there some document which lists the things that need to be taken
  care of before submitting the changes -- other open source projects
  like u-boot have such documentation which specifically mentions the
  do's and don'ts for patch submission.

This is my first mail to any netbsd mailing list, so apologies in
advance if i have broken any rules :)
