From 59f1ee104d1a6c04b0690b7c8ce481449da174d6 Mon Sep 17 00:00:00 2001 From: Mike Crowe Date: Fri, 8 Dec 2017 13:43:26 +0000 Subject: kernel.bbclass: Fix do_sizecheck behaviour During the introduction of support for multiple kernel image types in 849b67b2e4820564b5e5c9bd4bb293c44351c5f3, do_sizecheck was changed to only warn if any kernel was bigger than ${KERNEL_IMAGE_MAXSIZE}. (Well, it tried to warn - it turns out that there's no function called "warn", it should be "bbwarn".) The previous behaviour had been to fail the build if the single kernel image did not fit. It seems possible that people might be generating both compressed and uncompressed kernels and only really care whether the compressed one fits. This means that we shouldn't just always fail if any of the images are too large. So, let's warn (correctly this time) on every image that is too large, but only ultimately fail if no image will fit. The build will also fail if ${KERNEL_IMAGETYPES} is empty, but I hope that no-one needs to do that. While we're here correct a typo in the KERNEL_IMAGE_MAXSIZE validity check.
