From 0723c05fb75e4428b79b5cd657af7496b2604422 Mon Sep 17 00:00:00 2001 From: Olof Johansson Date: Thu, 16 Jul 2015 21:26:16 +0100 Subject: [PATCH] arm64: enable more compressed Image formats Plumb up Makefile arguments for the already supported formats in the kbuild system: lz4, bzip2, lzma, and lzo. Note that just as with Image.gz, these images are not self-decompressing and the booting firmware still needs to handle decompression before launching the kernel image.
