Add a driver for the designware serial UART used on sunxi. This just redirects to the normal ns16550 driver.
Add a stdout-path to the device tree so that the correct UART is chosen.

Should the UART related code in arch/arm/cpu/armv7/sunxi/board.c:gpio_init() be nobbled in this configuration?
Yes I think that needs attention. Ideally we should be able to have this handled by the serial driver (requesting the pinmux it needs) but we don't have infrastructure for that as yet.
Ah, I thought your earlier GPIO patches were that, but I suppose not.
Suggestions? What does the kernel do here?
It has pinmux infra.
In the meantime could we somehow replace/augment the #ifdef chain in gpio_init with something keyed off the stdout alias perhaps?
