Thanks Marc.

Your patch was too large for the mailing list.  Can you put future
versions online somewhere or send compressed?

I really don't like these big copyright banners.  I don't see much
point in copyrighting a header file.  SeaBIOS is LGPLv3, and all core
files must use that copyright.

This doesn't apply to non-core files copied from other projects, so
doesn't need to be true for tools/kconfig.

Also, your first patch modifies seabios, but I thought you were going
to do that in patch2?  I don't see a reason to have old way and new
way in parallel - lets just go right to the kconfig way.  The way
you've introduced configh.h, configu.h, and configk.h in addition to
the existing config.h is confusing.

Can you explain what this does?
