Let's be straight - the UEFI boot support in U-Boot is very much a limited project to ease booting; it's not *at all* a complete implementation of UEFI like Tianocore. It doesn't support any of the runtime interfaces, for example. I stand by my recommendation: for normal use for an end user on an arm64 machine, UEFI is a better bet than U-Boot. ... >> Last question: what should people do to keep armel?
