Is this the same as the Linux Kernel has in crypto/aes_generic.c? If
yes, then please use it. If no, then why not? ;)
Generally any crypto code should integrate into the barebox crypto API
(which is basically the same as the Linux crypto API). This is the main
road blocker that must be removed before we can merge this into barebox.
