Hi All,
 
I am trying to bring up MPC8548 CDS board on 2.4 kernel. I have problem in the head_e500.S. The "mtspr SRR0, r7; mtspr SRR1 r6" does not work for me. The content of R7 and R6 are not moved to SRR0 and SRR1.  I am using the tool-chain from Freescale for 2.6 kernel. 
 
Any idea on this issue?
 
Thanks,
 
Mike
