The TI watchdog timer is present on BeagleBone's. Since 2014, U-Boot
has been booting the BeagleBone with the watchdog enabled. We need to
disable it on boot to avoid a spurious reset.
The timer isn't exactly precise, but it will do as a watchdog. This
is also a reflection of the watchdog(9) API.
In the future, we could handle interrupts, but the watchdog(9) API
needs to be a bit smarter before that can happen.

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

We currently have 3 random_adaptors:

probe.c doesn't do anything other than picking a specific random_adaptor
from a list of registered ones.

creation of /dev/random is postponed until next random_adaptor is kldload'ed.
