Will you have time to port them to DT, or would you rather focus on
J-core systems ? Do those boards still boot a mainline kernel ?

Dropping Renesas SH board files doesn't preclude anyone from moving them
to DT, all the information will remain in the git history. Unless you
plan to move to DT in a reasonably near future, I think dropping support
for the CEU at least, if not the whole board files, could be a good
option.
