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.

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.

129 bool "Enable SDRAM location for SPL stack"
130 help
131 SPL starts off execution in SRAM and thus typically has only a small
132 stack available. Since SPL sets up DRAM while in its board_init_f()
133 function, it is possible for the stack to move there before
134 board_init_r() is reached. This option enables a special SDRAM
135 location for the SPL stack. U-Boot SPL switches to this after
136 board_init_f() completes, and before board_init_r() starts.

159 Some platforms need a large BSS region in SPL and can provide this
160 because RAM is already set up. In this case BSS can be moved to RAM.
161 This option should then be enabled so that the correct device tree
162 location is used. Normally we put the device tree at the end of BSS
163 but with this option enabled, it goes at _image_binary_end.
