recent changes in wic/bootimg-efi could break the image-installer.wks.in in case of large image. https://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/scripts?id=801f07fc00d43d107cb6ae671dbbb57ee91cc6be would be nice to have a way to tell wic/bootimg-efi to ignore IMAGE_BOOT_FILES.
image-installer.wks.in comes with 2 partition, ESP and "image" partition. the content for "image" partition are define by IMAGE_BOOT_FILES. The recent changes to allow bootimge-efi to take IMAGE_BOOT_FILES would cause 1. image file to duplicates in both partition. 2. error incase of large image file, due to 4 GB limit in ESP.
Issue fixed, related selftest content added and squashed in the same commit. Commit also have been merged. Commit link here: https://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?id=85574ce0cf84eaf828334dd2fafadc18909e73b5
