SPL is not supported by NXP software releases, so I would keep non-SPL
as the default.

Thanks,
Peng.

The main idea about this series is to follow latest U-Boot features
SPL, dts, dm so I drooped non-SPL configs, Once these changes are in
tree on next release, may be NXP will need to update these.

thanks!

I also prefer we keep the original non-SPL defconfigs.

Thanks

OK, but dtb-enabled is fine right? will ended up 3 configs for non-spl
and spl all have dtb-enabled.

thanks!

Enabling dtb support is fine. Keeping the DCD defconfigs is very convenient.
