Although, what the rest of the node used for? Do we expect to parse it?
I wasn't able to find a suitable bindings in the docs...
A reg can encode multiple regions, by just listing them one after the
other. It'll be in the generic docs about reg properties I expect,
there's nothing special about a reg property in a memory node in this
regard.
Xen parses these just fine, via the loop and use of device_tree_get_reg
in process_memory_node
I know that a "reg" can encode multiple regions... My question was
related to the "rest of the node" and not the rest of the property... i.e
region@10000000 {
contiguous-region;
reg = <0x10000000 0x1f800000>;
linux,phandle = <0x2>;
phandle = <0x2>;
};
AFAICT we don't parse it.
