Hmm, I remember Jordan didn't like the archive concept, and ISTR he
prefered fs, as suggested by the romfs name too. I think an *fs name
makes sense when there is a master structure like here.

I agree, but datablobs is not a great name either.. :)

Shouldn't 1. and 2. be in sync somehow?

Yeah. I don't know. :\ It depends on how early in the stack this
problem is relevant. For coreboot+SeaBIOS it will never become an
issue. Want to make use of more stuff - then maybe you need better
hardware. Does that seem fair?

I do however think it would suck to intentionally regress on m57sli,
or any other board.

As for the name I can not stress enough how important it is to come
as close as possible to something unique, especially when there is a
unique purpose (and noone has publically standardized firmware flash
chip content before), and this particular area is a very confusing
minefield for newcomers already. We lose way more by ignoring that
and making things worse than we can ever gain from the best technical
storage solution. :\

Even if we can't find the perfect name we will suffer for sure if we
have a name which can be confused or misunderstood in any way.

A good name alone lowers the knowledge barrier for many.

Sounds great!
