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

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

40 by running the command:

78 This option allows certain base U-Boot options and settings
79 to be disabled or tweaked. This is for specialized
80 environments which can tolerate a "non-standard" U-Boot.

85 bool "Init with zeros the memory reserved for malloc (slow)"
86 default y
87 help
88 This setting is enabled by default. The reserved malloc
89 memory is initialized with zeros, so first malloc calls
90 will return the pointer to the zeroed memory. But this
91 slows the boot time.
92
93 It is recommended to disable it, when CONFIG_SYS_MALLOC_LEN
94 value, has more than few MiB, e.g. when uses bzip2 or bmp logo.
95 Then the boot time can be significantly reduced.
96 Warning:
97 When disabling this, please check if malloc calls, maybe
98 should be replaced by calloc - if expects zeroed memory.

119 bool "Enable SDRAM location for SPL stack"
120 help
121 SPL starts off execution in SRAM and thus typically has only a small
122 stack available. Since SPL sets up DRAM while in its board_init_f()
123 function, it is possible for the stack to move there before
124 board_init_r() is reached. This option enables a special SDRAM
125 location for the SPL stack. U-Boot SPL switches to this after
126 board_init_f() completes, and before board_init_r() starts.

178 new boards should not use this option.
