Hi Jan,
Apologies for the delayed response, I was off over the Christmas. Thank
you for your thorough review and for testing the patch on top of U-Boot
next.

You are correct, both of these configs are missing from the defconfig.
I am not quite sure how I managed to miss those in creation of this
patch, thanks for catching that.

Apologies, I got ahead of myself. When I sent this patch the above two
patches I sent had not yet been merged. They are now both merged to
next & master.
Thanks again for your feedback and for sharing your working queue.
Should you need me to send a v2 to add the missing two configs or have
any other issues please let me know, however, with the addition of the
two configs, this should now be good to go.
Thanks again,
Jamie.
