Hi Geert,

while backporting this and similar changes for other boards
to v3.14/LTSI-3.14 I noticed that koelsch, alt and ape6evm-reference
come up without a console. Which is not ideal.

I am wondering if you have any thoughts on why this may occur.
My wild stab in the dark is some interaction with PM.

For reference my backport is the backport/v3.14.23/snapshot2.wip1 tag in my
renesas-backports tree. At the very top it includes reversions of the
backports of the troublesome patches.
