It should be timing issue in the SoC, software did not have a proper
process to handle
IMMR registers accessing.

I agree Kumar on this.
Adding the read back with load is needing for the LAW window changing.
And something like sync/eieio instruction also need to be added between
stw and lwz...
to have a proper order accessing.

Thanks,
