But in this case the duplicated code is not small -- there are 1224
lines of code in 8 files that are shared verbatim and would need to be
copied. Its fairly meaty stuff, and the only differences between boards
are generally *very* small. (PCI routing, a few registers moved, and
thats about it.)
The truly board-specific bits are individual files. Right now the
meatiest of these is the dbau1550 config at 345 lines.
Frankly, almost all of these boards are going to have more in common
with the DBAU15XX boards than the DBAU15XX boards have in common with
each other or with the PB1XXX boards.
I'd prefer to avoid duplicating code everywhere. :-)
Maybe we need something like this:
