scan pci -Devices are not detected

["vishnuvaradan vishnuvaradan" <vishnuvaradanr@xxxxxxxxx>]

Hi,

Iam using Xfree4.7.0 crosscompiled on a 7448 powerpc board with Marvell system controller
Marvel PCI 0 is connected to PMC site in which PMC silicon motion vga card is used
Marvel PCI 1
 has TSI 148 chip.
The devices are not detected on running scanpci ... Help me to solve the issue 

----------------------------------results----------------------------------------------------------------------------------------------------------

on running ./scanpci  it displays only

pci bus 0x0000 cardnum 0x01 function 0x00: vendor 0x10e3 device 0x0148
