pc could be null if hosttype != BCMA_HOSTTYPE_PCI.
If we are on a device without a pci core this function is called with
pc = null by b43 and brcmsmac. If the host type is PCI we have a pci
core as well and pc can not be null.

Some SoCs have a PCIe host controller to make it possible to attach
some other devices to it, like an other Wifi card.
This code was tested with an Netgear WNDR3400 (bcm4716 based), but
should work with all bcma based SoCs.

bcma_core_pci_hostmode_init() has to be in __devinit as it will call a
function in that section and so all functions calling it also have to
be in __devinit.

There are many magic numbers used in the PCIe code. Replace them with

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.

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.
The cores are getting the same numbers as before.

Function managing IRQs is needed for external drivers like b43.
On the other side we do not expect writing any hosts drivers outside of
bcma, so this is safe to do not export functions related to this.

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.
