6 | Enabling this option will pass "-O2" to gcc when compiling | |
7 | under "lib" directory. | |

16 | depends on HAVE_PRIVATE_LIBGCC | |
17 | help | |
18 | This option allows you to use the built-in libgcc implementation | |
19 | of U-boot instead of the one privided by the compiler. | |

30 | config SYS_VSNPRINTF |
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. | |

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

51 | config SHA1 | |
52 | bool "Enable SHA1 support" | |
53 | help | |
54 | This option enables support of hashing using SHA1 algorithm. | |
55 | The hash is calculated in software. | |
56 | The SHA1 algorithm produces a 160-bit (20-byte) hash value | |
57 | (digest). | |

62 | This option enables support of hashing using SHA256 algorithm. | |
63 | The hash is calculated in software. | |
