Hello Takahiro Akashi,
With latest kexec-tools, I have moved little further
Here’s what I get. Is this correct?
kexec -p /run/media/mmcblk0p1/vmlinux --initrd=/run/media/mmcblk0p1/fsl-image-ls2085ardb.ext2.gz
kexec version: 16.03.14.10.05-gef652df-dirty

Try gzip decompression.
Try LZMA decompression.
