I don't understand what you mean about including code fragments from
romstage. It is for memory setup and only used in romstage.

I thought about a kconfig setting, but that seems to abuse kconfig.
It isn't a feature, so much as an setting override.  If we want to put
items like in kconfg, we should do it for all the items in mcti.h.
This can also get a little strange as the options start to rely on
other kconfig settings.
