The memory node corresponds to struct meminfo and each entry (with two
values) makes one struct membank defining a memory bank.
I've been talking with Kyungmin about this. Originally bootloaders used to
report 4 banks of 256 MiB, but it turned out that real bank configuration
on Trats is 2 banks of 512 MiB.
I'm not into memory management internals, so I don't know if this has any
significance, but I defined the node to represent the real configuration
(otherwise I would have probably used 4 banks of 256 MiB and drop the 4th
patch).

Right.
