[ixp1200] IXP 1200 reset.

[Kameswara Avasarala]

Hi,
        Is there anyway by which we can reset the IXP from the host ? 
 Since the IXP CSR is accessible from the host  I tried the following
1) Wrote  0xFFFFFFFF into the IXP1200_RESET register
2)Enabled Timer 4 (watchdog) and zeroed (atleast I thought I did) out 
the timer from the host.
Writing into the IXP1200_RESET register does not work even from the SA 
itself whereas the watchdog works.
Thanks,
Kamesh.
