37 reduces the code size by about 2.5KiB on armv7.

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

111 If this option is set, support for LZ4 compressed images
112 is included. The LZ4 algorithm can run in-place as long as the
113 compressed image is loaded to the end of the output buffer, and
114 trades lower compression ratios for much faster decompression.
115
116 NOTE: This implements the release version of the LZ4 frame
117 format as generated by default by the 'lz4' command line tool.
118 This is not the same as the outdated, less efficient legacy
119 frame format currently (2015) implemented in the Linux kernel
120 (generated by 'lz4 -l'). The two formats are incompatible.
