32 | bool "Enable tiny printf() version" | |
33 | help | |
34 | This option enables a tiny, stripped down printf version. | |
35 | This should only be used in space limited environments, | |
36 | like SPL versions with hard memory limits. This version | |
37 | reduces the code size by about 2.5KiB on armv7. | |
38 | ||
39 | The supported format specifiers are %c, %s, %u/%d and %x. | |

57 | help | |
58 | The faster memset() is the arch-specific one (if available) enabled | |
59 | by CONFIG_USE_ARCH_MEMSET. If that is not enabled, we can still get | |
60 | better performance by writing a word at a time. But in very | |
61 | size-constrained envrionments even this may be too big. Enable this | |
62 | option to reduce code size slightly at the cost of some speed. | |

71 | help |
72 | This enables support for TPMs which can be used to provide security | |
73 | features for your board. The TPM can be connected via LPC or I2C | |
74 | and a sandbox TPM is provided for testing purposes. Use the 'tpm' | |
75 | command to interactive the TPM. Driver model support is provided | |
76 | for the low-level TPM interface, but only one TPM is supported at | |
77 | a time by the TPM library. | |

124 | If this option is set, support for LZ4 compressed images | |

126 | compressed image is loaded to the end of the output buffer, and | |
127 | trades lower compression ratios for much faster decompression. | |
128 | ||
129 | NOTE: This implements the release version of the LZ4 frame | |
130 | format as generated by default by the 'lz4' command line tool. | |
131 | This is not the same as the outdated, less efficient legacy | |
132 | frame format currently (2015) implemented in the Linux kernel | |
133 | (generated by 'lz4 -l'). The two formats are incompatible. | |
