What else can we do?

Not realy. The original BSD terms would still apply, but additional ones
might be added. Hence we can't known the exact licensing terms for a
custom version (or from git, or tarball).

Oh so it has come to this? I'm the guy making things complicated? ;-)

As you said, there is not much we can do about the custom versions. For
all we know, the developpers may have also completely ripped-off the
license text and moved it somewhere else (e.g. to suite whatever their
legal department might have invented).

So, if it were just for me, I'd move all the licensing information into
the conditional code:

    ifeq ($(BR2_TARGET_ARM_TRUSTED_FIRMWARE_LATEST_VERSION),y)
    ARM_TRUSTED_FIRMWARE_LICENSE = BSD-3-Clause
    ARM_TRUSTED_FIRMWARE_LICENSE_FILES = license.txt  # Valid for v1.4
    endif

And be done with it.

Yann E. MORIN.
