apart from dt_binding_check error are we OK with dt bindings ?

As I had mentioned in the other patch, I'd prefer if we can create
standard binding for representing the memory regions. IMHO we should
create subnode for memory regions Each sub-node itself may or may not
have more than one memory region.

In your platform, since there can be only one allocation in a memory
region, there should be 4 sub-nodes for each of the memory region and
each node should have page_size (or some equivalent property) property
to indicate page_size (= region_size).

For a platform that doesn't have the restriction, there can be a single
sub-node containing all the memory region.

Let's wait for Rob's comment though.

Thanks
Kishon
