This is a subset of pl011 UART which does not supprt DMA or baud rate changing.
It is specified in the Server Base System Architecture document from ARM.
Is there any reason not to consider submitting this as a TTY driver now - are there known problems other than the issues with ACPI in general (I've not reviewed the code at all)? The ACPI binding in this case seems particularly safe since it's a purposely basic and unconfigurable IP.
I guess we may want to consider handoff to the full pl011 driver at some point but there's a bunch of stuff with clocks to worry about before then.
