Hi
Thanks for the patches.

I think the change to the wayland imx should go into its own recipe. The change is unrelated to the weston imx update.

Additionally I would reword the weston patch to make it clear it is about the imx fork, e.g. weston: Upgrade from 12.0.3.imx to 12.0.4.imx

Looks good to me.

Thank you @MaxKrummenacher I rebased the branch to include latest commits from Freescale:master

I think this merge should wait the linux-imx bump. Other than that I think it's ok

Good, just squash the change in the previous commit and push it again to the branch, so I can merge it.

Done, sorry for that, now should be ok
