a big "Dankeschön" for all your work, which eventually ended up in a
true turn-key solution for the problem.  The only things I had to add
were a few bumps of the copyright dates, plus your name into the
copyright notices of the two files you've been reworking (eeprom.h,
eeprom.S).  I just committed everything to both, after verifying at
least the rudimentary EEPROM IO (on an ATmega16, and an ATmega48 which
is one of those that weren't supported before).

A similarly big "Thanks" (or rather "Spasibo") goes to everybody who
reviewed these routines, and commented on them, so Björn could
subsequently improve them.

I'm not much of an expert on this, but that looks OK to me.  The
linker map file shows that the .text.eeprom section is linked
