This is a relatively low-cost AST2500-based Xeon E-2100/E-2200 series
mini-ITX board that we hope can provide a decent platform for OpenBMC
development.

This initial device-tree provides the necessary configuration for
basic BMC functionality such as host power control, serial console and
KVM support, and POST code snooping.

The patch looks good! Some minor things below.

When sending subsequent versions, make sure to add -v N to your git
format-patch to mark it as the Nth version.

You've also set this to be threaded with a previous version of the
patch. We normally don't do that, and in this case it's doubly
confusing as you've split this patch out from the previous series.

I noticed you cc'd soc@kernel.org. We normally only do this when we
want the soc maintainers to apply a patch directly without going
through another maintainer. In this case the patch should go through
the aspeed maintainer's tree (me), so you don't need to cc that
address.

Hmm, that came from using './scripts/get_maintainer.pl --no-rolestats' 
with git send-email's --cc-cmd flag; does there happen to be a similarly 
easy alternative that wouldn't do the "wrong" thing there?

Ack on the rest, will send v3 soon.


Thanks,
Zev

This spot just here is where you should put the changes between v1 and v2.

The device tree itself looks good!

If you fix up the things I mentioned and send a v3 I will apply it.

Cheers,

Joel
