Thanks. But I do think it is part of my previous patches :-). 
My patches mainly contains
(1) Move 86xx pcie support to powerpc/sysdev/fsl_pcie.c and 
change some CONFIG Option.
(2) Add 8548 pcie support based on fsl_pcie.c. Add PCIE ATMU for 8548.
(3) Remove some reluctant code in fsl_pcie.c.
(4) Add link status check for pcie.
(5) Unify 85xx/86xx pcie mmu register define.
(6) Add device tree for 85xx cds legacy board.

The code for PCIE ATMU and link status check are from Wei Zhang. 
The patches have been tested for both 85xx/86xx boards and merged to the
85xx git repo. in opensource.freescale.com

I do not touch the code for common pci/e architecture because more
discussions
might be needed. I had thought to add the  85xx pcie support early. I
received
too many request for its support.
Thanks.
