If it was as "plain and simple" as you say, there would be nothing to
argue about. What we ended up with is 2 or 3 level hierarchy of nodes which
doesn't at all seem to be such simple (considering the fact that what's
covered by a the simple "bank-width" property could be represented by several
combinations of interleaved flash chips). So, what you wanted us to do was
either substantially redesign Linux MTD subsys to fit it into that model
(either that or over-engineer the physmap_of driver to gather that kind of
information from the multiple "chip" subnodes). Guess how well would that
have been accepted even if we had time to do that...
