It would be nice if one of the maintainers or the remaining users could go
through the code though and figure out which bits are definitely dead
(e.g. sh5), don't build, or are incomplete and not worked on for a long
time, compared to the bits that are known to work and that someone
is still using or at least playing with.
I guess a lot of the SoCs that have no board support other than
the Hitachi/Renesas reference platform can go away too, as any products
based on those boards have long stopped updating their kernels.
