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.

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

127 If this option is set, support for LZ4 compressed images
128 is included. The LZ4 algorithm can run in-place as long as the
129 compressed image is loaded to the end of the output buffer, and
130 trades lower compression ratios for much faster decompression.
131
132 NOTE: This implements the release version of the LZ4 frame
133 format as generated by default by the 'lz4' command line tool.
134 This is not the same as the outdated, less efficient legacy
135 frame format currently (2015) implemented in the Linux kernel
136 (generated by 'lz4 -l'). The two formats are incompatible.
