Andy,
Sure, but until freescale or someone else with eq. and motivation researches it, we are stuck. I am not sure anyone else has tried 83xx based boards yet. If someone has please report. Also include weather booted from NAND or NOR, CPU type(e300cX) and what reset vector is used.
I have a couple of Freescale reference boards here (8313ERDB and 8349-MITX-GP). I'm not a powerpc expert by any means but if there are some (simple) tests you would like me to run on them then I will see if I can find some time.
I can see this issues only on MPC837x, i.e. *not* on MPC834x.

sorry.
I meant that e.g. mvblm7 board (=MPC8343) works like a charm from current mainline U-Boot.
My latest MPC8377 board does not even start without your suggested 4 nops. It does not start (i.e. serial line completely dead) with any USB functionality defined. I also have random hangs depending on activated code, e.g. CONFIG_CMD_something or SPI drivers etc.
To me it looks like an alignment problem *somewhere*.
As said before I'm still digging and try to get more useful information.
Do you think porting the board to an earlier (maybe 2009) version is worth a try ? I could start bisecting if we could get a stable version.
Regards, André
