what about the ones from CIX like the orangepi or their framework mainboard? (though I agree, I miss UEFI for all its faults)
Those are currently suffering from high power draw because they have to keep the cores awake for memory speeds. Lackluster performance as well, but thats the problem with the majority of the ARM ecosystem ever since apple started crafting SoCs.
i hope, but i dubt that will be mass produced.. so no economy of scale
You do actually get UEFI on a few of these, though personally I've always fared better with U-Boot. (Sooner or later, I always run into something that is a simple edit in the device tree or uEnv, but UEFI doesn't expose.)
