> But we need to ignore licencing for a used defined official ATF version.
> 
> Althougt the ATF version are licensed under BSD-3-Clause, the license

> 
> Ignore the licencing check if the user provide a custom official version.

I've switched to using positive logic, with the _LATEST _variable, which
makese the condition even more explicit, too:

    ifeq ($(BR2_TARGET_ARM_TRUSTED_FIRMWARE_LATEST_VERSION),y)
