-Broadcom BCM47xx Partitions
-===========================
-
-Broadcom is one of hardware manufacturers providing SoCs (BCM47xx) used in
-home routers. Their BCM947xx boards using CFE bootloader have several partitions
-without any on-flash partition table. On some devices their sizes and/or
-meanings can also vary so fixed partitioning can't be used.
-
-Discovering partitions on these devices is possible thanks to having a special
-header and/or magic signature at the beginning of each of them. They are also
-block aligned which is important for determinig a size.
-
-Most of partitions use ASCII text based magic for determining a type. More
-complex partitions (like TRX with its HDR0 magic) may include extra header
-containing some details, including a length.
-
-A list of supported partitions includes:
-1) Bootloader with Broadcom's CFE (Common Firmware Environment)
-2) NVRAM with configuration/calibration data
-3) Device manufacturer's data with some default values (e.g. SSIDs)
-4) TRX firmware container which can hold up to 4 subpartitions
-5) Backup TRX firmware used after failed upgrade
-
-As mentioned earlier, role of some partitions may depend on extra configuration.
-For example both: main firmware and backup firmware use the same TRX format with
-the same header. To distinguish currently used firmware a CFE's environment
-variable "bootpartition" is used.
-
-
-Devices using Broadcom partitions described above should should have flash node
-with a subnode named "partitions" using following properties:
-
-Required properties:
-- compatible : (required) must be "brcm,bcm947xx-cfe-partitions"
-
-Example:
-
-flash@0 {
- partitions {
- compatible = "brcm,bcm947xx-cfe-partitions";
- };
-};
