      bcma: add Broadcom specific AMBA bus driver · 8369ae33
      Rafał Miłecki authored
      
      
      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.
