+Subject: [PATCH 15/21] bcma: scan for extra address space
+
+Some cores like the USB core have two address spaces. In the USB host
+controller one address space is used for the OHCI and the other for the
+EHCI controller interface. The USB controller is the only core I found
+with two address spaces. This code is based on the AI scan function
+ai_scan() in shared/aiutils.c i the Broadcom SDK.

+It is used in bcma_core_set_clockmode() and bcma_core_pll_ctl() to

+This adds a USB driver using the generic platform device driver for the
+USB controller found on the Broadcom bcma bus. The bcma bus just
+exposes one device which serves the OHCI and the EHCI controller at the
+same time. This driver probes for this USB controller and creates and
+registers two new platform devices which will be probed by the new
+generic platform device driver. This makes it possible to use the EHCI
+and the OCHI controller on the bcma bus at the same time.

+Subject: [PATCH 20/30] USB: Add driver for the ssb bus
+
+This adds a USB driver using the generic platform device driver for the
+USB controller found on the Broadcom ssb bus. The ssb bus just
+exposes one device which serves the OHCI and the EHCI controller at the
+same time. This driver probes for this USB controller and creates and
+registers two new platform devices which will be probed by the new
+generic platform device driver. This makes it possible to use the EHCI
+and the OCHI controller on the ssb bus at the same time.
+
+The old ssb OHCI USB driver will be removed in the next step as this
+driver also provide an OHCI driver and an EHCI for the cores supporting
+it.

+Subject: [PATCH 6/6] MIPS: BCM47xx: Remove CFE console
+
+Do not use the CFE console. It causes hangs on some devices like the
+Buffalo WHR-HP-G54.
+This was reported in https://dev.openwrt.org/ticket/4061 and
+https://forum.openwrt.org/viewtopic.php?id=17063
