Right, taking register snapshots is currently beyond the scope of
omapconf.

However, as I suggested earlier in this thread, if we had a new driver
with read/write interface where register snapshots are saved, I imagine
adopting omapconf to read from such an interface for dumping register
snapshots would be relatively easy, right?

[1] again, I haven't really thought much about this, but something like;
write an address to /dev/foo, then reading 'len' bytes from /dev/foo
would give back the snapshot data (if any) starting from that address.
