Submitting patches

[Martin Bonner]

I and my colleagues have a number of patches we would like to
contribute back to the community, however for various reasons
(principally operating inside corporate firewalls), it isn't possible
to use `git send-email`, and I haven't been able to create a plain
text email which is acceptable to `git am`.

Is it possible to fork u-boot on Git[HL][au]b or similar hosting site,
and then send an email to the list pointing at the commit?
