FWIW, you don’t need FreeBSD toolchain to build uboot — it’s a freestanding
application and does not depend on FreeBSD ABI.  Using a compiler from the
cross-gcc port will suffice.

You will need to provide TGTARCH=arm and TGTABI=eabi when building the toolchain.
There used to be a arm-rtems-gcc port available which provided packages, but
it was sadly removed along with other useful ports.  But if you’re using one of
the older FreeBSD version with full package collection you can install one by
running `pkg_add -r arm-rtems-gcc`.  Then build uboot with CROSS_COMPILE=arm-rtems-
variable set.
