No problem. If you can test and debug arm big-endian, that's apprecated.

Hello Niels,
sorry for the delay - I've been on vacation.

We still have the ARM BE CI ready to go. Is it maybe time to get it

I've now tried the same interleaving for salsa20 on x86_64, and it gives a
25% speedup on my laptop. Pushed to a new branch, x86_64-salsa20-2core.

I've added the fat build
I would like to help but I have no clue or experience with ARM NEON, sorry.

I've written some new ARM Neon assembly for salsa20. See
https://gitlab.com/gnutls/nettle/-/commit/2ac58a1ce729a6cfe1d3703f4deb6da8862909e9,
when configured with --enable-arm-neon.
It interleaves the processing of two blocks, which gives a speedup of
50% -- 100% on the ARM cores where I've tested
