| 31 | bool "Enable safe version of sprintf()" | |
| 32 | help | |
| 33 | Since sprintf() can overflow its buffer, it is common to use | |
| 34 | snprintf() instead, which knows the buffer size and can avoid | |
| 35 | overflow. However, this does increase code size slightly (for | |
| 36 | Thumb-2, about 420 bytes). Enable this option for safety when | |
| 37 | using sprintf() with data you do not control. | |

42 | help |
| 43 | If this variable is defined, U-Boot is linked against the | |
| 44 | SLRE (Super Light Regular Expression) library, which adds | |
| 45 | regex support to some commands, for example "env grep" and | |
