++Broadcom introduced new bus as replacement for older SSB. It is based on AMBA,
++however from programming point of view there is nothing AMBA specific we use.
++
++Standard AMBA drivers are platform specific, have hardcoded addresses and use
++AMBA standard fields like CID and PID.
++
++In case of Broadcom's cards every device consists of:
++1) Broadcom specific AMBA device. It is put on AMBA bus, but can not be treated
++   as standard AMBA device. Reading it's CID or PID can cause machine lockup.
++2) AMBA standard devices called ports or wrappers. They have CIDs (AMBA_CID)
++   and PIDs (0x103BB369), but we do not use that info for anything. One of that
++   devices is used for managing Broadcom specific core.
++
++Addresses of AMBA devices are not hardcoded in driver and have to be read from
++EPROM.
++
++In this situation we decided to introduce separated bus. It can contain up to
++16 devices identified by Broadcom specific fields: manufacturer, id, revision
++and class.
