U-Boot image Entry address

[Mori Hiroki]

Hi

We have entry address issue in last onion target talk in this ml.

I made script for entry address in my maintenance version ZRouter. 

https://github.com/yamori813/zrouter/blob/add_new_devices/tools/entryaddr.sh


This is use in physical address in mips target. Almost mips is use
0x80000000. But be careful RT2880 is use 0x88000000.

ARM terget is linked by kvm address(0xc0000000). Then convert to 
physical address.

This script use in Makefile in ZRouter.

Why I still use ZRouter. That reason my ar531x all target is Redboot.
I convenient ZRouter more than freebsd-wifi-build.

This is remote update ruby script for ZRouter build binary.

And I add cramfs support to ZRouter.

This is used by host's mkcramfs command.

Thanks
