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. | |
41 | ||
42 | (The actual string used here is the first eight characters produced | |
43 | by running the command: | |

150 | help | |
151 | The old configuration infrastructure (= mkconfig + boards.cfg) | |
ed36323f | 152 | provided the extra options field. If you have something like |
51631259 MY |
153 | "HAS_BAR,BAZ=64", the optional options |
154 | #define CONFIG_HAS | |
155 | #define CONFIG_BAZ 64 | |
156 | will be defined in include/config.h. | |
157 | This option was prepared for the smooth migration from the old | |
158 | configuration to Kconfig. Since this option will be removed sometime, | |
159 | new boards should not use this option. | |
