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)
CPU: AMCC PowerPC 460EX Rev.

Thanks a lot.
