Do you have a reason to keep using uImage instead of using zImage?
uImage are now a bit deprecated on ARM, and zImage is the modern way of
booting the kernel even from U-Boot (using the bootz command).

No problem, I applied them already.

Indeed. We don't have a solution for this in the upstream Buildroot.
However, people in this situation are encouraged to use the concept of
"defconfig" fragments, which can be merged together to give the final
defconfig.

I've applied your patch.

Thanks!
