Broadcom based home router devices use partitions which have to be discovered in a specific way. They are not fixed and there is not any standard partition table. This commit adds and describes a new custom binding for such devices.

None of the existing platforms connect the R/B pin to a GPIO (they all use one of the dedicated R/B pin). Anyway, if we ever get short of native R/B pins, it's probably better to fallback to STATUS reg polling than trying to poll a GPIO.
