[U-Boot] Problem with transparent PCI-PCI bridge on Canyonlands

Can you turn on the additional debug information. That will give a
better
Clue as to what part is hanging.

Hi,

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
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
what could be wrong in u-boot ? I'll post a separate question to 
linuxppc-dev.

U-Boot 2009.11-rc2-00002-g386118a (Dec 09 2009 - 18:48:44)

       Bootstrap Option H - Boot ROM Location I2C (Addr 0x52)
       Internal PCI arbiter enabled
       32 kB I-Cache 32 kB D-Cache
Board: Canyonlands - AMCC PPC460EX Evaluation Board, 2*PCIe, Rev. 14

Thanks a lot.

Felix.
