The only one I know of is MACH_WLF_CRAGG_6410, as Mark Brown
has pointed this one out as being used as the testbed for Wolfson/Cirrus
audio codecs. The machine is also the only one that shows being worked
on from the git history. The last patches I found that look like they were
boot tested on other machines include work by Kukjin Kim in 2015 and by
Sergio Prado in 2016, but I don't see which boards they were using, and
I don't think they still care. Thomasz Figa had access to multiple
machines back in 2014, but he converted those to use DT.
If we follow the same approach that I'm suggesting for the other
platforms and nobody else speaks up, that would leave only the DT
boards plus the Cragganmore.
