Keyword substitution: kv
Default branch: MAIN

Remove unused snprintb format strings.

General code cleanup:
 - use generic macros for building IO and IOBDMA addresses instead
   of many different variations of the same theme.
 - use #define's for CVMSEG addresses instead of magic numbers.
 - use __BIT/__BITS/__SHIFTIN/__SHIFTOUT in most places, instead of
   foo_SHIFT defines or (worse) shifting by magic numbers.

No functional changes.

Add a few more bits.
XXX convert to __BITS.
--
If bus_space_map fails, just don't attach the driver instead of panicing.
Check RNG built in self test, don't attach if that fails too.
--
Oceton RNG/RNM driver modernisation to fit new entropy world order by
riastradh@, with some tweaks to get working in RNG mode.
XXX TODO: work out how to get raw entropy mode working.
--
Rework octeon_rnm(4) random number generator driver.
- Do a little on-line self-test for fun.
- Draw raw samples from the ring oscillators.
- Draw substantially more samples:
  =3D> early RO samples seem to have considerably lower entropy
  =3D> consecutive RO samples are not independent
- Make sure to use rnd_add_data_sync in the callback.
  =3D> not technically needed in HEAD, but would be needed for pullup
--
Adjust entropy estimate for the Octeon.
We are hedging in serial and in parallel, and more conservative than
the Linux driver from Cavium seems to be, so although I don't know
exactly what the thermal jitter of the device is, this seems like a
reasonable compromise.

Rework octeon_rnm(4) random number generator driver.

- Do a little on-line self-test for fun.
- Draw raw samples from the ring oscillators.
- Draw substantially more samples:
  => early RO samples seem to have considerably lower entropy
  => consecutive RO samples are not independent
- Make sure to use rnd_add_data_sync in the callback.

Initial import of Cavium Octeon and Octeon Plus SoC and
specifically Ubiquiti Networks EdgeRouter LITE support.
Currently the ethernet and uart are worked.
This support was contributed by Internet Initiative Japan Inc.
