Nice job! It's great to see a finished product story posted here; don't see
that too often. I'll keep an eye on it as you finish & test it (especially wrt
convergence time, jitter and dispersion).
I noticed a few minor things:
* The schematics all (or almost all) appear to be the same interface board,
rather than display, PS, PS monitor, etc. File names are right, but contents
are not.
* You might want to add the GPL comment to your power.a51 code
* I was a little confused when you configured ntpd without PPS support, but
then I saw you manually tweaked config.h later. I guess that's because ntpd
doesn't know about your PPS driver?
* The variable HZ patch seems a little dodgy to me, but I haven't dealt much
with 2.4 kernels. What HZ did you end up using?
The (very) recent vanilla 2.6 kernels integrate PPS support directly, but you
would have to add back the ep93xx HRT support and the TS SD support, so it's
probably not worth it.
