Btw, booting with systemd as init causes a lot of hickups which I didn't see

(The second trace is redundant, I actually meant to post the two traces only

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.

Hi Yoshinori and Rich,
can you take a look and possibly pick up the series below that untangles
and sorts out minor issues with the sh ioremap and dma code?
I sent this out a few times, but never got an answer. If you don't
want to pick up the series I can also take it through one of my trees
