Hi all, I found that the arm64 kernel doesn't support for compressed kernel image. In this way, the bootimage with android may be much bigger than compressed version.
Who can tell the reason of this? I will be appreciated it!

It is better to implement decompression in the bootloader where you don't have to worry about relocating yourself and already have console and caches enabled. Otherwise you have to duplicate that functionality in the self decompressor as arm32 does.
