[u-u] freebsd on raspberry pi

[William Waites]

>From chatter on the freebsd-arm list it might be better to wait a little
(or build your own image) depending on what you want to do with it. The
reason is, as I understand it, that the support for hardware floating
point on ARM is mature enough that they are in the process of making it
the default. The process of upgrading a soft-fp installation sounds a
bit hairy.

On the BBB, some success this weekend:

  - Now booting off the internal flash (easy when you know how to do it,
    but completely undocumented and not easy to figure out, will try
    to fix that).
  - The EEPROM and RTC on the cryptocape now working but the latter
    needed putting a driver from -current into 10.3. This makes the
    cryptocape graduate from "interesting" to "useful" because the BBB
    does not have an RTC.
  - Got the extra serial ports enabled, in particular the one for
    communicating wth the ATMega328p microcontroller on the cryptocape.
    This is also poorly documented for FreeBSD and doing it is related
    to but different from how you do it with Linux and this will be true
    of the R-Pi as well if you need to enable or disable particular
    peripheral hardware.
