+Subject: [PATCH] ARM: BCM53573: Initial support for Broadcom BCM53573 SoCs
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+BCM53573 series is a new family with embedded wireless. By marketing
+people it's sometimes called Northstar but it uses different CPU and has
+different architecture so we need a new symbol for it.
+Fortunately it shares some peripherals with other iProc based SoCs so we
+will be able to reuse some drivers/bindings.
