The R40 is the successor to the A20. It is a hybrid of the A20, A33 and the H3.
The R40's PIO controller is compatible with the A20, Reuse the A20 UART and I2C muxing code by adding the R40's macro.
The display pipeline is the newer DE 2.0 variant. Block enabling video on R40 for now.

You should really wrap that line too (and CONFIG_VIDEO below).
Kconfig doesn't seem to like line wrapping. I can split both into 1 symbol per line though. Would that be taking it to far?
Something like:
default y if MACH_SUN8I_A23 default y if MACH_SUN8I_A33
?
I didn't know it was possible.. But if it works, yes, please that will even be easier to review / extend.
Thanks! Maxime
