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.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
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.
This patch adds support for using bcma on a Broadcom SoC as the system
bus. An SoC like the bcm4716 could register this bus and use it to
searches for the bcma cores and register the devices on this bus.
BCMA_HOSTTYPE_NONE was intended for SoCs at first but BCMA_HOSTTYPE_SOC
is a better name.

Subject: [PATCH 10/14] bcm47xx: prepare to support different buses
Subject: [PATCH 08/22] 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.
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 10/22] 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
