Awesome! Nice to have these patches escaping the lab :)

In terms of naming suggestions: I think this depends on what we're
looking to emulate here. I see two options:

The qemu platform becomes a "reference" for OpenPOWER bmc hardware, but
doesn't necessarily align with an actual machine. In that case,
something generic like opbmc-<SoC> would make sense.

On the other hand, if we'd like to create qemu platforms that represent
actual machines (eg, the OpenPOWER "palmetto" machine), then
<PLATFORM>-bmc would seem more appropriate. In this case, the machine
name would be palmetto-bmc. No need to include the SoC name in that, as
it's defined by the hardware implementation.

I think the latter option may be more generally useful.
