[U-Boot-Users] TQM866M CPU glitch

[Nicholas Mc Guire]

Hi !

 I have a TQM866M board here, and it seems that the ID that this board is
 using is not checked for in cpu/mpc8xx/cpu.c - not sure if this patch is
 usable - but it fixes the problem of indentifying the right CPU for me

A different issue is that I can't get the ehternet to work, the error on 
network access is:
...
TX not ready
TX timeout
...

Any known issues with ehtnernet on TQM866 ? could not find anything in the list
except for SRAM issues (that seem not to exist any way) - any hint would be 
appreciated.

thx!
