This driver provides a small set of functions for handling the interface to the SIB. Because the SIB board contains such a diverse set of hardware functions, this driver simply provides the basics, such a board discovery and address configuration.

The typedef for _SIB_Info. |
|
|
Get SIB addressing information. Obtain the addresses and sizes of the SIB board memory regions and registers. The BSP function pciFindDevice() is used to scan the bus for an SIB board. Both the flight/EM model and evaluation model SIB boards are recognized. This function only supports a single instance of the SIB board on the PCI bus, so the first board found is queried. The info structure is filled in with the SIB hardware values upon success. Because the evaluation model SIB board does not include the PDU/GASU or heater control hardware, those registers are marked with address 0xffffffff. The addresses which are returned in the info structure are already mapped into CPU local address space and ready for direct use by client drivers. Users should note, however, that the SIB memory regions reside on the little-endian cPCI bus and byte ordering must be taken into account on PPC targets. This function is optimized so that the cPCI bus scan is only done on the first call. Thereafter, a cached copy of the SIB_Info structure is kept.
