From: Ed Swarthout <Ed.Swarthout(a)freescale.com>
All of the PCI/PCI-Express driver and initialization code that
was in the MPC8641HPCN port has now been moved into the common
drivers/fsl_pci_init.c. In a subsequent patch, this will be
utilized by the 85xx ports as well.
Common PCI-E IMMAP register blocks for FSL 85xx/86xx are added.
Also enable the second PCI-Express controller on 8641
by getting its BATS and CFG_ setup right.

Wolfgang,
Please apply this to the testing repository as it depends on
my previous PCI/PCI-E changes already applied there. I have
built and tested this on the 8641 from u-boot-testing.
Thanks,
jdl
