I see this in a lot of your Kconfig changes, the spacing is
wrong/inconsistent, please fix to be a single tab of indentation.

I feel this should be doing something under/with drivers/reset/ instead.

Do you really need to support non-DT kernels?  CONFIG_MACH_TYPE should
likely not be used here.

Ugh, I see that line made it back in, in another board.  That's not
meaningful.

TAGS are part of Kconfig, if you _really_ need them still.  Please make
use of CI:
https://u-boot.readthedocs.io/en/latest/develop/ci_testing.html
to make sure the series passes there as we have tests to catch things
which need to be in Kconfig not board.h files such as this and some
others that follow.

Please just use the default baudrate table.

Is this coming in unmodified from Linux?  Thanks!
