I will re-send the patches once I've applied the relevant fixups from
the last round, hopefully within the next few hours.

We currently have enough to use the system. And yes, we boot with
board-lager-reference.c which current seems to be turning up bugs
in the up-stream (see the recent new bug with cpg clock code reported
by my colleague).

Due to issues out of our control we can test with board-lager.c but
we must use the board-lager-reference.c for actual product test. The
only way we found around this is ugly hacking of the core driver code
to link platform and fdt devices...
