Actually, 'rt' is not a single part is it? If the variations are same 
die, but fused off then no need to distinguish. Otherwise, these should 
be SoC specific.

I don't exactly know what "but fused off" means I would assume
disconnected but on-die? The imxrtxxx is a series that has the same UART
controller across them. Should I add ACK?

Same applies to other compatible strings.
