I think that's the main point of the discussion and the confusion. The current
implementation in the fsl-community-bsp is a single-EULA system. The user
accepts only a single EULA in setup-environment.

But in fact every recipe which uses the "fsl-eula-unpack" bbclass downloads a
software tarball which may contain another version of the EULA. Some recipes
like 'firmware-imx' (checked on fido) put the Licence/EULA from the software
tarball in the LIC_FILES_CHKSUM variables:

    LIC_FILES_CHKSUM = "file://COPYING;md5=acdb807ac7275fe32f9f64992e111241"

That is, I think, the correct behaviour

Other recipes don't do this like 'imx-gpu-viv'. The recipe only contains

    LIC_FILES_CHKSUM = "file://gpu-core/usr/include/gc_vdk.h;beginline=5;endline=11;md5=12c028cbbbedb4b8770267131500592c"

although there is a file 'COPYING' in the software tarball which contains a
version of Freescale EULA.

If it's a single-EULA system, the global EULA in "sources/meta-fsl-arm/EULA",
which is presented to the user, should be deployed along the package (as my
patch did). This also means that the all software is actually covered by that
single EULA whether or not the software tarball contains the exact same copy of
the EULA in the file COPYING. And my patch doesn't break any builds because the
md5sum is only checked against the global EULA file, not the actual EULA in the
downloaded software tarball.

If it's a multi-EULA system, the user should be able to accept every EULA
separately. The already mentioned LICENSE_FLAGS mechanism [1] in Yocto can be
used for that. It also supports some sort wild-care enabling to accept a range
of licences, but that is transparent to the user.

Mit freundlichen Grüßen / Kind regards,

I fear you'll need to pass all the pain we passed back then, once again.
