148 +Broadcom introduced new bus as replacement for older SSB. It is based on AMBA,
149 +however from programming point of view there is nothing AMBA specific we use.
150 +
151 +Standard AMBA drivers are platform specific, have hardcoded addresses and use
152 +AMBA standard fields like CID and PID.
153 +
154 +In case of Broadcom's cards every device consists of:
155 +1) Broadcom specific AMBA device. It is put on AMBA bus, but can not be treated
156 + as standard AMBA device. Reading it's CID or PID can cause machine lockup.
157 +2) AMBA standard devices called ports or wrappers. They have CIDs (AMBA_CID)
158 + and PIDs (0x103BB369), but we do not use that info for anything. One of that
159 + devices is used for managing Broadcom specific core.
160 +
161 +Addresses of AMBA devices are not hardcoded in driver and have to be read from
162 +EPROM.
163 +
164 +In this situation we decided to introduce separated bus. It can contain up to
165 +16 devices identified by Broadcom specific fields: manufacturer, id, revision
166 +and class.
