|
+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.
