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.

90 for the low-level TPM interface, but only one TPM is supported at

140 If this option is set, support for LZ4 compressed images
141 is included. The LZ4 algorithm can run in-place as long as the
142 compressed image is loaded to the end of the output buffer, and
143 trades lower compression ratios for much faster decompression.
144
145 NOTE: This implements the release version of the LZ4 frame
146 format as generated by default by the 'lz4' command line tool.
147 This is not the same as the outdated, less efficient legacy
148 frame format currently (2015) implemented in the Linux kernel
149 (generated by 'lz4 -l'). The two formats are incompatible.
