+config LZ4
+ bool "Enable LZ4 decompression support"
+ help
+ 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+ This is not the same as the outdated, less efficient legacy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.

+ The function errno_str(int errno), returns a pointer to the errno
+ corresponding text message:
+ - if errno is null or positive number - a pointer to "Success" message
+ - if errno is negative - a pointer to errno related message
