21 | The string you set here will be appended after the contents of | |

34 | A string of the format -gxxxxxxxx will be added to the localversion | |

101 | bool "Enable SDRAM location for SPL stack" | |
102 | help | |
103 | SPL starts off execution in SRAM and thus typically has only a small | |
104 | stack available. Since SPL sets up DRAM while in its board_init_f() | |
105 | function, it is possible for the stack to move there before | |
106 | board_init_r() is reached. This option enables a special SDRAM | |
107 | location for the SPL stack. U-Boot SPL switches to this after | |
108 | board_init_f() completes, and before board_init_r() starts. | |

151 | help |
152 | The old configuration infrastructure (= mkconfig + boards.cfg) | |

51631259 MY |
154 | "HAS_BAR,BAZ=64", the optional options |
155 | #define CONFIG_HAS | |
156 | #define CONFIG_BAZ 64 | |
157 | will be defined in include/config.h. | |
158 | This option was prepared for the smooth migration from the old | |
159 | configuration to Kconfig. Since this option will be removed sometime, | |
160 | new boards should not use this option. | |
