FWIW, you don=E2=80=99t need FreeBSD toolchain to build uboot =E2=80=94 =
it=E2=80=99s 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=3Darm and TGTABI=3Deabi 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=E2=80=99re=
 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=3Darm-rtems-
variable set.=20
