prblem Initializing the PCIe Bridge at u-boot

[김영환]

Hi,

I am using to the LSI SAS MEGARAID SAS 8480E adapter. And I am under
debugging u-boot-1.2.0. u-boot-1.2.0 and kernel-2.6.20(denx's git) don't
include the code to scan and setup under pcie bridge, Right?

 I have checked the LSI adapter at general linux system. The structure of
the LSI Adapter is the following. I don’t know exactly why only bridge
find and setup at u-boot. Help me please.
