What is the status of these dts files with upstream Linux?  They need to
be in linux-next at least before we take them.

There shouldn't be a space today where there is, so this entry can just
fill in that gap.

DM_ETH should always be set, so please clean this up.

Please find someplace better than the board config.h file for these
values.  Either some SoC header file, or pulled out of the dt.  And
you're probably not the first board to do this, but it does need
cleaning up.

CONFIG_BOOTCOMMMAND is part of Kconfig, so this needs to be set in the
defconfig.  I didn't see any other options that need to be migrated,
but, CI will fail (at least, -next has the test fixed) over migrated
options being in the board config.h file.
