thanks, i have added the board to our list and will commit it later
together with other small changes.

hm yes, that is indeed a minor problem. please note that the voltages
are not used (yet) to change the actual voltage on programmers that
support this feature.
your solution is not convincing though. one problem is, that flashrom
is not only used with PC hardware. another one is that flashrom (and
the wiki) groups chips together that can not be distinguished by any ID
command (yet). it may be possible to distinguished the chips above with
some non-standard and/or extended ID command which has not been
implemented yet - i have not checked that.
in any case it might be a good idea to be able to add footnotes to
chips too and i have put that on my todo list.
the short-term solution would be a comment in flashchips.c on
all/many/some affected chips (at least the whole W25Q series is
probably affected). patches/findings welcome ;)
