Much of the code was common to begin with. There is one nit, which is likely
not an issue at all. With the old code, the AIM machdep would __syncicache()
the entire kernel core at setup. However, in the unified setup, that seems to
hang on the MPC7455, perhaps because it's running later than before. Removing
this allows it to boot just fine. Examining the code, the FreeBSD loader
already does syncicache of the full kernel, and each module loaded, so this
doesn't appear to be an actual problem.

This port failed to gain traction and probably only a couple Wii consoles

support was never implemented, so it was impossible to use any peripheral

'device adm1030' instead, and this has been updated in GENERIC and NOTES.

Much to my chagrin, PS3 support seems to have bitrotted somewhat since the

to be faulty. This should be fixed soon...
CAPABILITIES stuff required to make ssh work.
Hopefully, Book-E can eventually be added to GENERIC, which would avoid
this kind of issue with bitrot. That will require figuring out how to link

exception of POWER3-based systems when run in 64-bit mode. The main
development target, however, has been the PAPR logical partition support
that is the default target in KVM on POWER and QEMU -- mileage may vary
on actual hardware at present. Much of the heavy lifting here was done

* Make Yarrow an optional kernel component -- enabled by "YARROW_RNG" option.
The files sha2.c, hash.c, randomdev_soft.c and yarrow.c comprise yarrow.
* random(4) device doesn't really depend on rijndael-*. Yarrow, however, does.
* Add random_adaptors.[ch] which is basically a store of random_adaptor's.
random_adaptor is basically an adapter that plugs in to random(4).
random_adaptor can only be plugged in to random(4) very early in bootup.
Unplugging random_adaptor from random(4) is not supported, and is probably a
bad idea anyway, due to potential loss of entropy pools.
We currently have 3 random_adaptors:
+ yarrow
+ rdrand (ivy.c)
+ nehemeiah
* Remove platform dependent logic from probe.c, and move it into
corresponding registration routines of each random_adaptor provider.
probe.c doesn't do anything other than picking a specific random_adaptor
from a list of registered ones.
* If the kernel doesn't have any random_adaptor adapters present then the
creation of /dev/random is postponed until next random_adaptor is kldload'ed.
* Fix randomdev_soft.c to refer to its own random_adaptor, instead of a
system wide one.

As of FreeBSD 8, this driver should not be used. Applications that use
posix_openpt(2) and openpty(3) use the pts(4) that is built into the
kernel unconditionally. If it turns out high profile depend on the
pty(4) module anyway, I'd rather get those fixed. So please report any
issues to me.
The pty(4) module is still available as a kernel module of course, so a
simple `kldload pty' can be used to run old-style pseudo-terminals.
