+- Regular expression support:
+		CONFIG_REGEX
+                If this variable is defined, U-Boot is linked against
+                the SLRE (Super Light Regular Expression) library,
+                which adds regex support to some commands, as for
+                example "env grep" and "setexpr".
+
 - Device tree:
 		CONFIG_OF_CONTROL
 		If this variable is defined, U-Boot will use a device tree

+ * struct slre	slre;
+ * struct cap	captures[4 + 1];  // Number of braket pairs + 1
+ * ...
+ *
+ * slre_compile(&slre,"^(GET|POST) (\S+) HTTP/(\S+?)\r\n");

+ * }
+ *
+ * Supported syntax:
+ *	^		Match beginning of a buffer
+ *	$		Match end of a buffer
+ *	()		Grouping and substring capturing
+ *	[...]		Match any character from set
+ *	[^...]		Match any character but ones from set
+ *	\s		Match whitespace
+ *	\S		Match non-whitespace
+ *	\d		Match decimal digit
+ *	\r		Match carriage return
+ *	\n		Match newline
+ *	+		Match one or more times (greedy)
+ *	+?		Match one or more times (non-greedy)
+ *	*		Match zero or more times (greedy)
+ *	*?		Match zero or more times (non-greedy)
+ *	?		Match zero or once
+ *	\xDD		Match byte with hex value 0xDD
