Squashed in http://patchwork.ozlabs.org/patch/1232761/, and updated previous patch to conditionally built itss.o. see https://gitlab.denx.de/u-boot/custodians/u-boot-x86/commit/43709fa0888cc80648939ae1588307334e6cc267#ddd927c365d5269dbf9372226e38641da8d7c208_30_30 This way will keep bisectability. applied to u-boot-x86, thanks!
