This is initial support for the Pengpod 1000 tablet.  The display is
not currently working but the UART works fine and allows access to the
u-boot console.  Memory timing is fine and Linux boots from SD card
and runs OK.

Is Linux supported this dts or in ML? couldn't find either?

I haven't sent the .dts for Linux yet.  The U-Boot and Linux .dts was
identical when I first created it back in 2017 but they have diverged
slightly now, just with some different pinctrl bits in Linux.

I was going to send the Linux .dts after the U-Boot .dts was accepted,
in case there were changes needed.

It could be other way around, try to send Linux first.

Sent.  Out of interest, why Linux first?  I would have thought U-Boot
first; you can test the U-Boot .dts without Linux but you can't test the
Linux .dts without U-Boot :-)

Not may drivers support dt in U-Boot, still need to add. So sending
Linux make more reliable with node definitions and we sync few of the
nodes or sometimes all(atleast from Allwinner platform)
