As arm64 has slightly different expectations about load addresses, lets use a different set of default addresses for things like the kernel. As arm64 kernels don't come with a decompressor right now, reserve some more space for really big uncompressed kernels.

Thanks, looks good to me applied to:
http://git.denx.de/?p=u-boot/u-boot-sunxi.git;a=shortlog;h=refs/heads/next
This will be part of my first pull-req for u-boot v2016.07.
Regards,
Hans
