	278	bool "Enable LZ4 decompression support"
	279	help
	280	If this option is set, support for LZ4 compressed images
	281	is included. The LZ4 algorithm can run in-place as long as the
	282	compressed image is loaded to the end of the output buffer, and
	283	trades lower compression ratios for much faster decompression.
	284
	285	NOTE: This implements the release version of the LZ4 frame
	286	format as generated by default by the 'lz4' command line tool.
	287	This is not the same as the outdated, less efficient legacy
	288	frame format currently (2015) implemented in the Linux kernel
	289	(generated by 'lz4 -l'). The two formats are incompatible.
