| config LOCALVERSION |
| string "Local version - append to U-Boot release" |
| 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" |
| 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".) |
| |
| config CC_OPTIMIZE_FOR_SIZE |
| bool "Optimize for size" |
| default y |
| help |
| Enabling this option will pass "-Os" instead of "-O2" to gcc |
| resulting in a smaller U-Boot image. |
| |
| This option is enabled by default for U-Boot. |

| config SYS_MALLOC_F |
| bool "Enable malloc() pool before relocation" |
| default 0x400 |
| help |
| Before relocation memory is very limited on many platforms. Still, |
| we can provide a small malloc() pool if needed. Driver model in |
| particular needs this to operate, so that it can allocate the |
| initial serial device and any others that are needed. |

| This option allows certain base U-Boot options and settings |
| to be disabled or tweaked. This is for specialized |
| environments which can tolerate a "non-standard" U-Boot. |
| Only use this if you really know what you are doing. |

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

| config FIT |
| bool "Support Flattened Image Tree" |
| help |
| This option allows to boot the new uImage structrure, |
| Flattened Image Tree. FIT is formally a FDT, which can include |
| images of various types (kernel, FDT blob, ramdisk, etc.) |
| in a single blob. To boot this new uImage structure, |
| pass the the address of the blob to the "bootm" command. |

| depends on DM |
| select RSA |
| help |
| This option enables signature verification of FIT uImages, |
| using a hash signed and verified using RSA. If |
| CONFIG_SHA_PROG_HW_ACCEL is defined, i.e support for progressive |
| hashing is available using hardware, RSA library will use it. |
| See doc/uImage.FIT/signature.txt for more details. |

| config SYS_EXTRA_OPTIONS |
| string "Extra Options (DEPRECATED)" |
| help |
| The old configuration infrastructure (= mkconfig + boards.cfg) |
| provided the extra options field. If you have something like |
| "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. |
