+- Safe printf() functions
+               Define CONFIG_SYS_VSNPRINTF to compile in safe versions of
+               the printf() functions. These are defined in
+               include/vsprintf.h and include snprintf(), vsnprintf() and
+               so on. Code size increase is approximately 300-500 bytes.
+               If this option is not given then these functions will
+               silently discard their buffer size argument - this means
+               you are not getting any overflow checking in this case.

 - Boot Delay:  CONFIG_BOOTDELAY - in seconds

                set to -1 to disable autoboot.
