21 | Append an extra string to the end of your U-Boot version. |
22 | This will show up on your boot log, for example. |
23 | The string you set here will be appended after the contents of |
24 | any files with a filename matching localversion* in your |
25 | object and source tree, in that order. Your total string can |
26 | be a maximum of 64 characters. |

33 | This will try to automatically determine if the current tree is a |
34 | release tree by looking for git tags that belong to the current |
35 | top of tree revision. |
36 | |
37 | A string of the format -gxxxxxxxx will be added to the localversion |
38 | if a git-based tree is found. The string generated by this will be |
39 | appended after any matching localversion* files, and after the value |
40 | set in CONFIG_LOCALVERSION. |

43 | by running the command: |

110 | images of various types (kernel, FDT blob, ramdisk, etc.) |

130 | The old configuration infrastructure (= mkconfig + boards.cfg) |
131 | provided the extra options field. If you have something like |
132 | "HAS_BAR,BAZ=64", the optional options |
133 | #define CONFIG_HAS |
134 | #define CONFIG_BAZ 64 |
135 | will be defined in include/config.h. |
136 | This option was prepared for the smooth migration from the old |
137 | configuration to Kconfig. Since this option will be removed sometime, |
138 | new boards should not use this option. |
