-Subject: [PATCH 08/26] bcm47xx: prepare to support different buses
-
-Prepare bcm47xx to support different System buses. Before adding
-support for bcma it should be possible to build bcm47xx without the
-need of ssb. With this patch bcm47xx does not directly contain a
-ssb_bus, but a union contain all the supported system buses. As a SoC
-just uses one system bus a union is a good choice.

-Subject: [PATCH 10/26] bcm47xx: add support for bcma bus
-
-This patch add support for the bcma bus. Broadcom uses only Mips 74K
-CPUs on the new SoC and on the old ons using ssb bus there are no Mips
-74K CPUs.

-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.

-Subject: [PATCH 19/26] USB: Add driver for the bcma bus
-
-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 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
