Just to make sure, that there is no misunderstanding. I am not
proposing to updating to GCC 7.2 and the latest IASL in the coreboot
toolchain for the coreboot 4.7 release. My proposal is, that all the
boards are made compatible with these new versions, and that these
patches are added to the coreboot 4.7 release.


Thanks,

Paul
