These are now in tty-next:

    10c63443b74d1ef5 Revert "serial: sh-sci: Remove SCIx_RZ_SCIFA_REGTYPE"
    a1c2fd7e1098ea49 Revert "serial: sh-sci: Allow for compressed SCIF address"

Can you please include them in v4.19-rc6, as they fix a regression introduced
in v4.19-rc1?

In addition:

    3d8b43ad9c0cf023 serial: sh-sci: Add earlycon for R7S9210

(also in tty-next) enables earlycon on RZ/A2 again, as it was disabled
by the two
reverts above.

Thanks a lot!

Gr{oetje,eeting}s,

                        Geert
