This option enables a tiny, stripped down printf version.

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

If this option is set, support for LZ4 compressed images

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This is not the same as the outdated, less efficient legacy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