| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* bcma: add Broadcom specific AMBA bus driverRafał Miłecki2011-05-1013-0/+1384
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.
