Note assuming you're using linux-sunxi kernels and not upstream kernels you also need "Enable workarounds for booting old kernels" for things to boot at all on A20 based devices,
IIRC there is also an env var which can be set to force booting in secure mode?
because the new u-boot by default boots the kernel in non secure mode (so that it can be a hypervisor and hw accelerated qemu-kvm works on the A20), but the old kernels do not work when booted in non secure mode (another bug in the old kernels, for which no fix is available).
(probably some mainline commits to head.S to handle boot in hyp mode could be backported, ignoring the actual KVM stuff)
