/************************************************************

* sysPciAutocinfigInclude - Specify devices to configure

* This routine returns TRUE for each device that the

* BSP needs to have configured.

* This hypothetical board had on-board power management

* controller as a PCI device and on-board video controller.

* Neither of those devices are supported by the BSP, but

* we want to configure everything else.

* Note that the PCI_ID_PM and PCI_ID_VIDEO macros are

* defined in the bspname.h file, as the device and

* vendor IDs of those devices:

* #define PCI_ID_PM ( ( PCI_PM_DEVICE << 16 ) | PCI_PM_VENDOR )

* #define PCI_ID_VIDEO ( ( PCI_VIDEO_DEVICE << 16 ) | PCI_VIDEO_VENDOR )

* RETURNS: N/A

STATUS sysPciAutoconfigInclude

(

PCI_SYSTEM *pSys,

PCI_LOC *pLoc,

UINT devVend

)

{

/* skip the local host bridge */

if ( ( pLoc->bus == 0 ) && ( pLoc->device == 0 ) )

return ERROR;

switch (devVend)

{

case PCI_ID_PM: /* Exclude Power Management */

case PCI_ID_VIDEO: /* Exclude Video */

retVal = ERROR;

break;

/* Include Everything Else */

default:

retVal = OK;

break;

}

return (retVal);

}

* intIrqTable - interrupt line assignments for autoconfig’d devices.

* This table includes the IRQ number for each PCI interrupt source

* on the board. The table is organized by a [bus, device, pin]

* tuple, since each [bus, device] pair identifies a unique physical

* location on the PCI bus, and each routine with that location

* can choose to use a different interrupt pin.
