The string generated by this will be 39 appended after any matching localversion* files, and after the value 40 set in CONFIG_LOCALVERSION. 41 42 (The actual string used here is the first eight characters produced 43 by running the command: 44 45 $ git rev-parse --verify HEAD 46 47 which is done within the script "scripts/setlocalversion".) 48 49config CC_OPTIMIZE_FOR_SIZE 50 bool "Optimize for size" 51 depends on !SPL_BUILD 52 default y 53 help 54 Enabling this option will pass "-Os" instead of "-O2" to gcc 55 resulting in a smaller U-Boot image. 56 57 This option is enabled by default for U-Boot. 58 59menuconfig EXPERT 60 bool "Configure standard U-Boot features (expert users)" 61 help 62 This option allows certain base U-Boot options and settings 63 to be disabled or tweaked.
