temporary mapping created by locore so that the lowest two to four
megabytes can become a permanent identity mapping. This implementation
avoids any use of a large page mapping.
FreeBSD/arm installworld install is only 170MB. The smallest SD card
I could find at the store today was 512MB (and it was only $10 after
rebate), with a 2GB card for as low as $25.00...
Now that the IIC stuff has been sorted out, include that as well.
Include hints for the icee 16kb 16-bit i2c device. It should include
info about the temperature sensor as well, but that driver isn't quite
ready.
Add bpf for dhclient happiness.

some devices (and not others). To get instances onto the iicbus, one
now needs hints or an identify routine. We also do not probe the bus
for devices because many iic devices cannot be safely probed (and when
they can, the probe order turns out to be somewhat difficult to get
right).

robustness of IIC transactions when parts aren't present. This also
removes a bunch of debug. This also moves this driver to 7-1
addressing rather than 6-0 addressing, which is more inline with all
the other iic drivers in the tree. I've tested this for about a
million years on the systems at work.
The relevant changes for FreeBSD (excerpt from the release note):
* Newly implemented CORE EXT words: CASE, OF, ENDOF, and ENDCASE. Also
added FALLTHROUGH, which works like ENDOF but jumps to the instruction
just after the next OF.
* Bugfix: John-Hopkins locals syntax now accepts | and -- in the comment
(between the first -- and the }.)
* Bugfix: Changed vmGetWord0() to make Purify happier. The resulting
code is no slower, no larger, and slightly more robust.
o tcp_input() now handles TCP segment sanity checks and preparations
including the INPCB lookup and syncache.
o tcp_do_segment() handles all data and ACK processing and is IPv4/v6
agnostic.
Change all KASSERT() messages to ("%s: ", __func__).
The changes in this commit are primarily of mechanical nature and no
functional changes besides the function split are made.

- Change exca_activate_resource() to call BUS_ACTIVATE_RESOURCE() before
calling exca_(io|mem)_map() since the latter use rman_get_bus(tag|handle)
and the recent changes to nexus(4) mean that you need to activate a
resource before reading the bus tag and handle. This was true before,
but now the nexus(4) drivers on x86 and ia64 are more forceful about it.

then call rt_setgate(). Third, change rt_ifa.
With this change we are able to change a link level route to a
gateway one, that wasn't possible before:

an arbitrary rt_entry.
