This series fixes the serial issues we're seeing on the sc7180 based
(sc7180-trogdor-lazor-limozeen and sc7180-trogdor-kingoftown) boards that we
have hooked up to KernelCI. Out of a 10-job batch of boot tests all succeeded
after the patch, whereas before most failed (7/10), due to a missing message in
the serial.

Tested-by: Nícolas F. R. A. Prado <nfraprado@xxxxxxxxxxxxx>

Looking forward to see this landed!

Thanks,
Nícolas
