Try the attached new port I just threw together for building u-boot for
this board. I have a different imx53 board so I haven't run-tested
this, but it builds for me on my x86 10-stable machine.
Unfortunately, this is the oldest u-boot source I've ever tried to work
with and most of the "standard freebsd u-boot patches" won't apply, so
this is pretty much exactly what comes from Rui's github branch. (I was
able to use the latest u-boot from denx for my imx53 board, but
apparently Digi never contributed their changes back to denx so this
ancient version is the only option right now.)
To use this diff, cd to your /usr/ports dir and apply the diff using:
patch -p0 </path/to/u-boot-ccwmx53.diff
Then just cd to /usr/ports/sysutils/u-boot-ccwmx53 and do "make install"
and you should end up with the u-boot files for your board installed
at /usr/local/share/u-boot
