Speaking of i.MX targets...
I have 2 different flavors of i.MX53-based development systems;
the i.MX53 Low-cost ("LoCo") board, and actually two complete
ConnectCore for i.MX53 JumpStart Kit for Android from Digi (which
are fairly high-end kits, retailing for about $500).
In fact, I have been waiting for any word on renewed interest or
momentum for the i.MX5/6 series. If someone is seriously interested
in attempting a port, I would consider sending them one of my i.MX53
ConnectCore kits, which is still unopened, in support of their efforts.
This kit is a good platform for porting, since it has just about every =
possible
peripheral available, including LCD, HDMI, WLAN, and even an SATA
drive interface.
A few months ago, I dived in deep, looking at some of the NetBSD port
code as well, but an ARM port of FreeBSD is still a little over my head.
While I have done tons of embedded development over the past 15 years,
this looks tough to do alone, or without prior FreeBSD/ARM driver =
experience.
Information on the boards I have are found at these links;

The i.MX5/6 are some nice ARM controllers -- I see some decent kits and
modules in several places;

Anyway, one interesting thing I noticed about the i.MX53 (and I suppose =
other
family members of i.MX series) was the boot loader, which is basically a =
ROM-
based BIOS boot loader, already built in, which can boot from several =
different
peripheral sources, and which can take certain peripheral configuration =
instructions
from a properly-structured table in the load record.
Maybe it's not too far over my head, if there were some collaboration, =
assuming
hardware available (which it is).
