--- Comment #1 from Konstantinos Margaritis (markos) <konstantinos at vectorcamp.gr> ---
First working version of xchacha_hchacha20() function, thanks to Luke for
making vertical-first usage clear!

https://git.libre-soc.org/?p=openpower-isa.git;a=blob;f=crypto/chacha20/src/xchacha20_svp64.s;h=4b5ce6e39504730481b4e8a846d32ac4bab6cc9c;hb=99bcb26563d29bbd36ac9d08d003ab1345850e46

Now, xchacha_encrypt_bytes() is left, but the main loop is the same, the rest
should be easy to implement.
