| 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. |
