So I've had a quick look about what could go possibly go away in our current armv8 config (using the pine64+ defconfig). Let me know if some are actually vitals: - FIT_ENABLE_SHA256_SUPPORT - CONSOLE_MUX - CMD_CRC32 - CMD_LZMADEC - CMD_UNZIP - CMD_LOADB - CMD_LOADS - CMD_MISC (actually implementing the command sleep) - ISO_PARTITION (yes. For CDROMs.) - VIDEO_BPP8, VIDEO_BPP16 - VIDEO_ANSI - SHA256 - LZMA Removing those options make the u-boot.itb binary size going from 516kB to 478kB, making it functional again *and* allowing us to enable the DT overlays that seem way more important than any feature mentionned above (and bumps the size to 483kB). Let me know what you think, Maxime -- Maxime Ripard, Free Electrons Embedded Linux and Kernel engineering http://free-electrons.com
