This patch integrates the LZ4 decompression code to the x86 pre-boot code. And it depends on two patchs below lib: Add support for LZ4-compressed kernel decompressor: Add LZ4 decompressor module Signed-off-by: Kyungsik Lee <kyungsik.lee@lge.com> --- arch/x86/Kconfig | 1 + arch/x86/boot/compressed/Makefile | 5 ++++- arch/x86/boot/compressed/misc.c | 4 ++++ 3 files changed, 9 insertions(+), 1 deletion(-)
