U-boot seems fine -- it's once I start the kernel that things start to go
wrong. Just tried a mainline 4.16-rc5, and I get the same kernel BUG fairly
early during boot (though no immediate panic).
Once thing I'm not clear on -- should I be using the dtb that came with the
kernel (arch/arm64/boot/dts/allwinner/sun50i-a64-olinuxino.dtb) or just use
the one provided by U-boot via $fdtcontroladdr?
Full boot log of 4.16-rc5 using the U-boot provided dtb follows.
