Sorry I don't understand what you mean.

What I meant is reserved-regions is some memory that have been carved out from 
the RAM. So the reserved-regions needs to be described in the memory node 
(memory@<addr>). We can either append them to the memory node created by 
make_memory_node. Or introduce new ones.
I haven't yet thought which one is more suitable.

Cheers,
