Please just use early_printk instead of reimplementing this.
I think it should work in this context too.

And please reuse the Linux code here.
Actually the best way to reuse would be to first do 64bit uncompressor
and linker directly, but short of that #includes would be fine too.

Can you please somehow reuse the Linux one?

Would be better to just pull in lib/string.c
