Pci scan

["Peerless Deepak" <peerlessdriver@xxxxxxxxx>]

Hi,

I am trying to find understand how the pci devices are enumerated on
kernel startup. I am concentrating on powerpc arch.

I could see  function called pcibios_init . Is it the starting point
for doing all device scan or whether the device tree is already formed
before this function.

Thanks for your time.

Regards
Deepak.P
