[Libre-soc-dev] daily kan-ban update 14may2021

[Lauri Kasanen]

Hi,

- prepared a cross toolchain to ppc64le
- refreshed my ffmpeg checkouts
- extracted C baselines for mp3 hotspots
- saved a set of test data for each, verified in C/x86
- split the mp3 bug to sub-bugs
- sent SSH key to Luke

I'd need a repo for the AV stuff, some help or pointers to docs on how
the simulator and asm converter run. Ideally I wouldn't have to write
python to run either, I don't really speak that. The mp3 spots are
float, so no elwidth or saturation needed yet. The counter change
discussed would be good soonish.
