Done. All are mapped now. However, some of the mappings may be

E.g., CON6001 had the LCM module's ID as its value. bom2part happily
picked this up as a direct ID match. I've now changed the value to
the connector number and put the (useful) reference to the module
below as F1.

Another example are the under-specified components: e.g., all we
know about L7602 is that it needs a 4.7 nH inductor in a 0402
package. There are two in the inventory, one by AVX and one by
Murata. The former has a tolerance of 0.3 nH while the latter has a
tolerance of 0.1 nH. Not sure if we care or not.

Below is a list of components for which we have multiple choices.
The first line has source and part number pairs, the second line
lists the component references.

R1513 and so on are tricky, because the only difference between the
two resistors is the tolerance, and we usually don't specify 5%. I
should probably just add a 5% default.

The KEVs look like something's wrong in my matching system. The rest
are probably caused by missing footprints.

Next: part2order comes up with overly pessimistic results. Have to
find out where it goes wrong.
