FWIW, I applied this patch, and booted the result successfully and without any user-visible changes on: - koelsch - armadillo-multiplatform - kzm9g-legacy - kzm9g-multiplatform
Armadillo-legacy is broken, and probably won't come back (cfr. https://lkml.org/lkml/2014/12/2/339).
Kzm9g-reference still hangs at "Calibrating local timer..." (it did work at some point in the past).
Note that my local tree is based on renesas-drivers-2014-12-08-v3.18, renesas-devel-20141212-v3.18, and yesterday's upstream, with CCF, PM domain, TWD, and lots of WIP patches from the kitchen sink applied.
Gr{oetje,eeting}s,
Geert
