So how do we proceed ? I have more coming on top of this, but we should
start with getting this series merged.

Greg, should we create a FSI git repo with a 3-member maintainer team
(Jeremy, Chris and myself) and send you pull requests ? Or are you
happy to continue picking up patches ?

We have more stuff to come in there, including support for a HW master
contoller in a future BMC chip, some more slave drivers, etc..

It also looks like the s390 guys might start using some of that as well
(their chips use FSI as well, so far they used our old service
processor which uses an ancient non-uptream set of drivers & stack, but
that's likely to change).

Cheers,
Ben.
