The screen turning off issue was caused by a deployment script copying the wrong
u-boot binary to the SD card! The patch does not introduce a regression on RPI 3
(tested before/after patch).

Once I switched over to the the real u-boot image the grub graphical font didn't
load (irrespective of patch) I was able to fix this by changing the


I suspect my issues are to do with DTBs and that all these problems will go away
once a single defconfig is available. The screen turning off issue I have no
