[U-Boot] PCIE Switch Support in u-boot-2015.01

[Ashish Khetan]

Hi,
I am using u-boot-2015.01 loader on MPC8641D based Board. I have following
queries Related to PCIe bus
1. Does it provide support to pcie switch(PES64H16AG2) support?
2. Do I need any specific driver for this switch to make it up?


After booting its not showing any link the logs are:
