mpc8315e: no link on pci-e interface

Hello,

I am currently designing an mpc8315e board with u-boot based on the mpc8315e-rdb board (u-boot v2011.06). One pci-e target is connected to pcie0 interface (mSATA SSD module), however during mpc83xx_pcie_init_bus call the pcie0 link returns always a "no link" information.

It looks like the mpc8315e-rdb code didn't include the serdes configuration has it's done on the mpc8308-rdb board, why such setting aren't present into mpc8315e-rdb?
Is the pci-e interface working on such board with the reset default configuration on serdes section?

Is someone has successful experience about the pcie0 interface with the mpc8315-erdb?

Thanks for your support,
Best regards
