Yes I am aware of the post stuff, but I have already expended great
effort integrating the boot progress stuff and I don't want to do
everything at once!

There is some scope to join bootstage and post, but for now they are
separate things with separate CONFIGs, and you don't have to enable
one to get the other.

Regards,
Simon
