What's this defined for , I see this is different against cv1800b.

CV1812h have a embedded 256MB RAM. The cv1800b is 64MB, This is why the
size is different. I write this node here because the RAM is embedded
and fixed size, and leave it in the board DT is unnecessary.

I can drop this include on application. Is the rest of the series okay
with you Chen Wang?

Yes, just remove this include and the others are all

Acked-by: Chen Wang <[email protected]>

I also ran dtbs check with W=1 and no warning found.

BTW, due to this patchset changes some code submitted by Jisheng, I have
sent email to him and hope he to have a look too.
