Summary

Nothing uses these anymore. They were for super small armv4 boards. Today, all
armv5 kernels boot via uboot which has its own compression scheme.

Maybe unifdef -UKZIP and have elf_trampoline.c changed too?

elf_trampoline.c should just be removed. With this change it will no longer be built.

This reference to KERNPHYSADDR can go too, it doesn't show up in ldscript.arm so the subsitution is a no-op here. The subsitution for KERNVIRTADDR is still vaild though.
