[OpenWrt-Devel] [PATCH v2 4/4] ramips: improve RBM11G partitioning

[Thibaut VARÈNE]

This patch improves faf64056ddd46992a75b1e277d94541c7251035c by updating
the partition scheme for the "RouterBoot" section of the flash.

This section is subdivided in several segments, as they are on ar71xx
RB devices, albeit with different offsets and sizes. The naming convention
from ar71xx has been preserved. The preferred 'fixed-partitions' DTS
node syntax is used, with nesting support as introduced in 2a598bbaa3.

Leave a note in DTS to explain how the original author selected the SPI speed.
