I suspect he got from the same place I did, freescales LTIB 
dev. env.

which has been patched to support 832x. I am having the 
same problem

as he has, any info on what the problem might be would be great.

Also, if anyone has any info on when these patches will be sent 
upstream, I sure would like to hear about it.

Hi Joakim,

Same here -- go into arch/ppc/platforms/83xx and edit file 
mpc83xx_sys.c.
If you are using the 8323e cpu, then you need to make sure
Yes, got one of those.
 
that file has code to support the 8323E.  Mine didn't, so I 
got no platform devices initialized (no serial port, no Eth 
devs).  I added a block of code to support the 8323E (set 
mask to 0xffff0000 and "value" to 0x80620000, then the device 
list for the 8323E).  Use existing code there as a guide, it 
was not difficult once I figured out that this was the problem.
hmm, you don't have a patch handy?
If you are using a newer LTIB release than me, perhaps yours is fixed.
The one I have is from 3/15/06.
Me too, I have requested that freescale release a new LTIB with proper support,
but who knows when the will be.
Anyway, this works fine for me and addresses the problem of 
the platform devs not getting initialized.
