I'm running latest u-boot on 1GHz Canyonlands board and have trouble using 64-bit transparent PCI-PCI PLX 6254 bridge. With PLX evaluation board plugged into Canyonlands PCI slot u-boot hangs. With PCI support

Where exactly does U-Boot hang?
What are the console messages you see? And which U-Boot version is this, and which version of the Canyonlands board?
disabled u-boot works fine. The PLX board is OK, it was recognized by both u-boot and kernel on Freescale MPC8536DS board. On Canyonlands linux-2.6.32 silently resets the board when PLX is plugged in. Any ideas

This is inconsistent: above you report U-Boot hangs, here you claim that Linux reboots?
As I said, if I disable PCI support in u-boot, it runs fine and can start booting linux.

Did you try running in another configuration, like 800-nor or 1066-nor?
I did try 600-nor and 800-nor, but that didn't change anything. With 1066-nor u-boot hangs earlier, the console messages show
