685a4ef0df bcma: add stub for bcma_bus_suspend()
.. and connect it up with the pci host bcma driver.

Now, the next step is to connect those bcma bus-level suspend/resume
functions to the actual bcma device suspend resume functions.

.. and avoid doing the unnecessary PCI operations - the PCI layer will
do them for us.

28e7d218da bcma: invalidate the mapped core over suspend/resume
This clears the currently mapped core when suspending, to force
re-mapping after resume. Without that we were touching default core
registers believing some other core is mapped. Such a behaviour
resulted in lockups on some machines.

439678f8b0 bcma: pci: use fixed windows when possible
Some cores are mapped in the fixed way, they registers can be accessed
all the time.

200351c77d bcma: add module.h to the modular portions of this driver
This will ensure that it continues to build once we remove
the implicit module.h presence from everywhere later on.

8369ae33b7 bcma: add Broadcom specific AMBA bus driver
Broadcom has released cards based on a new AMBA-based bus type. From a
programming point of view, this new bus type differs from AMBA and does
not use AMBA common registers. It also differs enough from SSB. We
decided that a new bus driver is needed to keep the code clean.

In its current form, the driver detects devices present on the bus and
registers them in the system. It allows registering BCMA drivers for
specified bus devices and provides them basic operations. The bus driver
itself includes two important bus managing drivers: ChipCommon core
driver and PCI(c) core driver. They are early used to allow correct
initialization.

Currently code is limited to supporting buses on PCI(e) devices, however
the driver is designed to be used also on other hosts. The host
abstraction layer is implemented and already used for PCI(e).

Support for PCI(e) hosts is working and seems to be stable (access to
80211 core was tested successfully on a few devices). We can still
optimize it by using some fixed windows, but this can be done later
without affecting any external code. Windows are just ranges in MMIO
used for accessing cores on the bus.
