Before new uImage code was merged, bootm code allowed for the kernel image to get overwritten during decompresion. new uImage introduced a check for image overwrites and refused to boot the image that got overwritten. This patch restores the old behavior. It also adds a warning when the image overwriten is a multi-image file, because in such case accessing componentes other than the first one will fail.
