kernel-yocto: ensure that only a single defconfig is processed
As a follow up to the changes to ensure that KBUILD_DEFCONFIG will always get its defconfig into the processing, we also should ensure that we don't get both a KBUILD_DEFCONFIG and a SRC_URI defconfig in the configuration queue. If both are in the configuration queue, we end up with competing values and a potentially long running check of 5000+ options x 2 against the final .config. By removing the defconfig found from the SRC_URI when one is found via KBUILD_DEFCONFIG, we ensure that only one will be processed. Signed-off-by: Bruce Ashfield <> Signed-off-by: Richard Purdie <>
