Please re-read my sentence.  I said "generally expect".

If you guys want to spend the man-years necessary to get ACPI and ARM 
working in U-Boot, go right on ahead.  I think it's a fool's errand.  I 
work on ARM Servers, so I know the pain that is ACPI.  You don't want 
it.  If your system works with device tree, stick with that.  ACPI has 
no value outside of ARM servers, and ARM servers already have UEFI.
