+config SYS_VSNPRINTF
+ bool "Enable safe version of sprintf()"
+ help
+ Since sprintf() can overflow its buffer, it is common to use
+ snprintf() instead, which knows the buffer size and can avoid
+ overflow. However, this does increase code size slightly (for
+ Thumb-2, about 420 bytes). Enable this option for safety when
+ using sprintf() with data you do not control.
+
+config REGEX
+ bool "Enable regular expression support"
+ default y if NET
+ help
+ If this variable is defined, U-Boot is linked against the
+ SLRE (Super Light Regular Expression) library, which adds
+ regex support to some commands, for example "env grep" and
+ "setexpr".
+
+config LIB_RAND
+ bool "Pseudo-random library support "
+ help
+ This library provides pseudo-random number generator functions.
