Lothar, All,

On 2018-10-09 15:25 +0200, Lothar Felten spake thusly:
> Add intial support for Bananapi M2 Ultra board based on the Allwinner
> R40 SoC.
> 
> - U-Boot 2018.07
> - Linux 4.18.12

Now that we have added support for the 4.19 linux kernel, this defconfig
no longer builds:

This also requires an explicit:
