It still does not feel right that you select only credit and NULL. Why not credit2 and NULL? Or other combination.

This patch is untested on Renesas RCar, please test!
Also, I am not sure whether some of the errata workarounds can be
disabled on the RCar.

Changes in v2:
- rename to rcar3
- only add required symbols, let the defauls take care of the rest

I am not sure what you mean here. Your .config below seems contains all the options including the non-selected one.

Also, this still not solving the problem raised by Andrew regarding keep them updated.

It might be easier to maintain if we provide a per platform config option (e.g CONFIG_RCAR3) that will select driver for that specific board.

The user is then free to select other components (e.g scheduler...). So you don't impose memaccess disabled, NULL scheduler...

(Thank you Andrii for the suggestion!)

+# CONFIG_NS16550 is not set
+# CONFIG_MVEBU is not set
+# CONFIG_PL011 is not set

IIRC the RCAR does not have an SMMU.
