The only minor thing I can think of here is that maybe this should be MSTARV7 to match the ARCH.
I'm not sure the PM UART is in the same place for the pre-ARMv7 stuff and for the MIPS stuff before that.

Aside from the MSTARV7 thing this looks good and I quickly tested on an SSD202D board.
With the MSTARV7 thing fixed if deemed necessary:
