+Subject: [PATCH] USB: bcma: separate code initializing USB 2.0 core
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This splits one big probing function into two smaller ones. The main one
+is now responsible for the generic stuff: allocating memory & enabling
+power using GPIO. The new one contains code that is specific to the USB
+2.0 bcma core.
+This will allow adding support for the USB 3.0 bcma core (handling XHCI)
+in the future.
