I think the mem=32M doesn't belong here, it's already specified in the memory
node.

I would prefer not to have any additional symbols selected by the board.
It's better to put those into the defconfig.

I'm not sure what the normal practice is these days regarding the 
board compatible table. I thought that we just put the soc name
in there for new platforms that are already DT-only. Your .dts
file contains both, so it works either way.
