Hello!

I have applied Christoph's full series on top of Linus' tree and I can confirm that
the kernel boots fine on my SH-7785LCR board.

Thus, for the whole series of patches:

Tested-by: John Paul Adrian Glaubitz <glaubitz@xxxxxxxxxxxxxxxxxxx>

However, independent of Christoph's series, the kernels throws two backtraces during
boot which I think should require a git bisect (unless I missed a configuration option
as I trimmed down the kernel a bit to make sure it's not too big).

See the traces below and let me know what you think.

Adrian
