I had problems with the BSP_pciFindDevice implementation, too.
I simply added a wrapper around pcib_find_by_devid()
(BSP_pciFindDevice API exists for sake of compatibility with
the PowerPC/shared BSPs):

Try

int
BSP_pciFindDevice( unsigned short vendorid, unsigned short deviceid,
                    int instance, int *pbus, int *pdev, int *pfun )
{
    int sig, rval;

    rval = pcib_find_by_devid(vendorid, deviceid, instance, &sig);

    if ( PCIB_ERR_SUCCESS == rval ) {
         *pbus = PCIB_DEVSIG_BUS(sig);
         *pdev = PCIB_DEVSIG_DEV(sig);
         *pfun = PCIB_DEVSIG_FUNC(sig);
    }

    return rval;
}
