[U-Boot] PCI Express Bus Scanning Issue

Hi

I am working on one MIPS based board ap91 which has x1 Pci Express 1.1 interface..There is only one host and one endpoint . But when i am using uboot commands OR any driver function (hose scan etc..) ,i am keep on getting devices on every bus...

Is there any bug or issue in Cmd_pci .c file ?/

Thanks Vaibhav
