I will leave this to someone who knows more about this and once someone
has decided which version of the firmware should actually be used.
Personally I have used 7.8 (from Yocto Warrior release) and 8.1 (from
Yocto Zeus release) with my custom i.MX8MM board so far.
The discussion about this is currently also going on here:
