ZTE is not the first one making such small customization on PL011, and likely won't be the last one. We don't want to clone PL011 driver every time there is a such vendor hardware coming out, do we? Having PL011 driver being able to handle different register layout is very helpful to handle such vendor variants, IMHO. I still appreciate rmk's insistence to handle ZTE device with PL011 driver, and the effort of adding a little "infrastructure" to handle all such possible variants.
