+Subject: [PATCH 01/14] bcma: move parsing of EEPROM into own function.
+
+Move the parsing of the EEPROM data in scan function for one core into
+an own function. Now we are able to use it in some other scan function
+as well.

+Subject: [PATCH 03/14] bcma: add functions to scan cores needed on SoCs
+
+The chip common and mips core have to be setup early in the boot
+process to get the cpu clock.
+bcma_bus_early_register() gets pointers to some space to store the core
+data and searches for the chip common and mips core and initializes
+chip common. After that was done and the kernel is out of early boot we
+just have to run bcma_bus_register() and it will search for the other
+cores, initialize and register them.

+Subject: [PATCH 04/14] bcma: add SOC bus
+
+This patch adds support for using bcma on an embedded bus. An embedded
+system like the bcm4716 could register this bus and it searches for the
+bcma cores then.

+Subject: [PATCH 05/14] bcma: add mips driver
+
+This adds a mips driver to bcma. This is only found on embedded
+devices. For now the driver just initializes the irqs used on this
+system.

+Subject: [PATCH 10/14] bcm47xx: prepare to support different buses
+
+The ssb bus is not hod directly any more. there is now a union which
+contains all the supported buses, now just ssb. As just one system bus
+can be used at a time the union does not cause any problems.

+Subject: [PATCH 12/14] 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.
