Two tiny & trivial patches with no regression risk. One simplifies
bcm53xx downstream patch.

+Subject: [PATCH] mtd: bcm47xxpart: add of_match_table with a new DT binding
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This allows using bcm47xxpart parser to find partitions on flash
+described in DT using the "brcm,bcm947xx-cfe-partitions" compatible
+property. It means this parser doesn't have to be explicitly selected by
+a flash driver anymore. It can be used e.g. together with a generic
+m25p80 / spi-nor if device is just properly described.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This allows using TRX parser to find TRX partitions on flash device
+described in DT using a proper binding. It's useful for devices storing
+firmware on a separated flash and having rootfs partition in it.
