Hans did a rebase on this version 2 and all patches apply OK.
I guess he also did build test with the remoteproc patch applied, 
and build fine. Yet, Jenkins were unable to check the build patch
per patch, due to the Kconfig issue.

Once the Kconfig issue has sorted out, feel free to send an updated
version, if something else is needed. On such case, please preserve
Hans SoB for the patches that won't require non-context changes.

Thanks,
