This patch improvesfaf64056ddby correcting the partition scheme for the "RouterBoot" section of the flash. The partition scheme initially submitted is incorrect and does not reflect the actual flash structure. The "RouterBoot" section (name matching OEM) is subdivided in several static segments, as they are on ar71xx RB devices albeit with different offsets and sizes. The naming convention from ar71xx has been preserved, except for the bootloaders which are named "bootloader1" and "bootloader2" to avoid confusion with the master "RouterBoot" partition. The preferred 'fixed-partitions' DTS node syntax is used, with nesting support as introduced in2a598bbaa3. "partition" is used for node names, with associated "label" to match policy set by6dd94c2781. Leave a note in DTS to explain how the original author selected the SPI speed.
