Here is one I used to build mine.  I didn't want to post it because I can't
guarantee it's correct.  My board has glitches with the PHY - could be
because of wrong parts or assembly issues (suspect the latter).

Probably only the Apache Labs have the correct BOM.

I don't think I will take this road again, i.e. building something as
complex as Hermes without having 100% correct documentation.
