Add device tree source for Renesas GR-Peach board.
GR-Peach is an RZ/A1H based board with 10MB of on-chip SRAM and 8MB
QSPI flash storage.
Add support for the board, and create a 2MB partition to use as rootfs.

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

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

Oh, I thought that was the SoC part number, and being both based on
RZ/A1H, I used the same.
Where can I find the correct part number?

Let's use gr-peach in place of grpeach everywhere then.

I assumed it had to match the SCIF number. Will change.

Was I the only one that had to go on Wikipedia to find out what a
mebibyte is :p ?
I'll drop comments here and in the rest of the patch.

Thanks, I'll change this.
Do we need to change that on Genmai as well while at there?
Some parts of its documentation report a frequency of 13.33Mhz, but X1
is listed in the BOM as
X1 XIN oscillator (socket mounted) SG-8002DC-13.3333MHz (Epson)

Add device tree source for Renesas GR-Peach board.
GR-Peach is an RZ/A1H based board with 10MB of on-chip SRAM and 8MB
QSPI flash storage.
Add support for the board, and create a 2MB partition to use as rootfs.
