This patch allows using a kernel image compressed with LZMA on ARM. Extracting the image is fairly slow, but it might be useful on machines with a very limited amount of storage, as the size benefit is quite significant (about 25% smaller with LZMA compared to GZIP) Tested-by: Martin Michlmayr <tbm@cyrius.com> Tested-by: Paulius Zaleckas <paulius.zaleckas@gmail.com> Signed-off-by: Albin Tonnerre <albin.tonnerre@free-electrons.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
