To fit the kernel image into the allotted space, a compressed kernel image is now needed. Use the Image.gz from the kernel build process and change the relevant places to use the new image name. This also necessitates adding an unzip command to u-boot to uncompress it to memory (and the loadm is still needed to setup the efi mem boot device). Also, the unzipped image is larger than before. So, increase the size that loadm is copying. This change shrinks the initramfs bundle size from 12MB to 4.8MB Signed-off-by: Jon Mason <jon.mason@arm.com> Signed-off-by: Abdellatif El Khlifi <abdellatif.elkhlifi@arm.com> Signed-off-by: Jon Mason <jon.mason@arm.com>
