Some of them are quite involved and this is a > risk for others. Yeah, I very much agree with this. Some of them are **very** involved, we don't really want to backport them. Speaking of which, maybe we should add some wording to SUPPORT.md about it? Currently it doesn't say anything specific about errata. > In this case, the erratum has already been implemented for other processors. > So the risk is minimal. > > > But as the official one will be on next Yocto release this would be ok to > > consider only 4.14 here. > > 4.14 only would be my preference. These ones are so trivial that apply straight away to all trees. I understand it is not your preference, but I'll backport them up until 4.12 unless you are strongly opposed to it.
