This doesn't seem like it should be a config option any more.
Ideally, it will become some automatic "as small as possible" configuration. Unfortunately ld doesn't allow to align everything to an upper boundary, so this requires the link-twice trick or so. So for now, I'd like to keep it there - people might want to tweak it. As an example (which made me look into this in the first place), someone (agaran) on #coreboot wanted to use a smaller bootblock. Until this automatically happens, we'll have to allow this to change.
Sounds good.
kconfig is just as good as any place in my opinion.
Yes.
