That part number is Genmai?

"renesas,gr-peach"?

The first serial port is supposed to be called serial0, unless labeled
otherwise.

bootargs = "ignore_loglevel rw root=/dev/mtdblock0";
stdout-path = "serial0:115200n8";

reg = <0x20000000 0x00a00000>;

No need for the comment, esp. since it says 10 megabits instead of
10 mebibyte ;-)

No need for the comment (megabyte vs. mebibyte)

Do we need the comment?

My schematics have one more digit of precision: <13333000>
