Sure. I was trying to fix the possible kernel hard lockup issues.

Currently OPAL doesn't know whether BMC is functioning or not.
If BMC is down and we keep on retrying sending message to BMC, we
will hit hardlockup issue in kernel.

So for now, I have added option to disable message retry in synchronous. On long run
we should get rid of synchronous.

Now this fix is not required in boot path. So I decided to get rid of this check 
in boot
path.

Hope this clarifies.
