Cool, thanks.

The board I have is labeled Creator Ci40, and grep'ing in the MIPS DT
files, led me to pistachio_marduk.dts.

This was given to me by Imagination a couple years ago, but I never had
the time to get it into kernelCI, and then the interest from Imagination
"went away." ;)

If nobody cares about this particular board, I don't really want to
waste any time on it either.  But, if there are other boards that people
actually care about we should integrate into kernelCI, and that someone
wants to donate, I'd prefer to setup those.
