Yocto Poky Linux (pyro) build warnings

Steve Pavao

When I try to build Yocto Poky Linux for Up Board with all repos in their 'pyro' stable release branches, I get the troublesome warnings listed at the end of this email.

May I ignore these warnings, or even better, if there's someone who knows how to alleviate this problem, it sure would be nice if the BSP layer(s) for meta-up-board and/or meta-intel could be tweak to avoid this issue altogether. pyro branch is supposed to be a stable release branch for all supported targets.

Thanks in advance for any ideas you may have.

Hi
I will have a look at it
they are warning for some configuration not set in the kernel you can ignore them for now
