config LOCALVERSION string "Local version - append to U-Boot release" depends on !SPL_BUILD help Append an extra string to the end of your U-Boot version. This will show up on your boot log, for example. The string you set here will be appended after the contents of any files with a filename matching localversion* in your object and source tree, in that order. Your total string can be a maximum of 64 characters. config LOCALVERSION_AUTO bool "Automatically append version information to the version string" depends on !SPL_BUILD default y help This will try to automatically determine if the current tree is a release tree by looking for git tags that belong to the current top of tree revision. A string of the format -gxxxxxxxx will be added to the localversion if a git-based tree is found. The string generated by this will be appended after any matching localversion* files, and after the value set in CONFIG_LOCALVERSION. (The actual string used here is the first eight characters produced by running the command: $ git rev-parse --verify HEAD which is done within the script "scripts/setlocalversion".) |

"HAS_BAR,BAZ=64", the optional options #define CONFIG_HAS #define CONFIG_BAZ 64 will be defined in include/config.h. This option was prepared for the smooth migration from the old configuration to Kconfig. Since this option will be removed sometime, new boards should not use this option. |
