Please pardon myself for being that annoying but it looks like 2018.02-rc1
was recently cut and that patch is not there yet.
It would be really cool if we may still get this one merged ASAP so
it becomes a part of the upcoming release.
FWIW the board was now officially released, see
https://www.synopsys.com/dw/ipdir.php?ds=arc-hs-development-kit
and we're looking forward to have more people working with that
quite capable board.
