Dpartition.txt1 Flash partitions in device tree
7 Different devices may be partitioned in a different ways. Some may use a fixed
8 flash layout set at production time. Some may use on-flash table that describes
12 To assist system software in locating partitions, we allow describing which
14 a subnode of the flash device that is named 'partitions'. It must have a
20 hierarchical (multi-level) layouts and should be used if there is some
21 significant relation between partitions or some partition internally uses
24 Available bindings are listed in the "partitions" subdirectory.
27 Fixed Partitions
30 Partitions can be represented by sub-nodes of a flash device. This can be used

Dbrcm,bcm947xx-cfe-partitions.txt1 Broadcom BCM47xx Partitions
5 home routers. Their BCM947xx boards using CFE bootloader have several partitions
6 without any on-flash partition table. On some devices their sizes and/or
7 meanings can also vary so fixed partitioning can't be used.
9 Discovering partitions on these devices is possible thanks to having a special
13 Most of partitions use ASCII text based magic for determining a type. More
14 complex partitions (like TRX with its HDR0 magic) may include extra header
