This supersedes #48, and adds the symbiflow toolchain package

We really need to make sure that there is a connection between these assets and the symbiflow-arch-defs git revision and not use the random latest version....

So this needs to download the results which match the git revision used to generate the package metadata. That info should be available in the shell environment somewhere...

As we've been discussing this internally, our current approach is to:

  • have a separate CI flow that checks the latest revision and rebuilds the package with the same revision name
  • have the package listed explicitly in target project's environment

This PR is a stub we begin with, based on the work we started ~1 year ago

Is there a simple way to go from symbiflow-arch-defs git revision number to the build CI output?

If so, you could use that process so that the contents are determined by the symbiflow-arch-defs git revision the package is built with?

Actually the git revision number is present within the link contained in https://storage.googleapis.com/symbiflow-arch-defs-gha/symbiflow-toolchain-latest.

For instance, the current latest link is the following:

https://www.googleapis.com/download/storage/v1/b/symbiflow-arch-defs/o/artifacts%2Fprod%2Ffoss-fpga-tools%2Fsymbiflow-arch-defs%2Fcontinuous%2Finstall%2F474%2F20211130-000503%2Fsymbiflow-arch-defs-install-8842ce79.tar.xz?generation=1638277014446946&alt=media

Where 8842ce79 is the sha of the most recent commit that generated the arch files in arch-defs: f4pga/f4pga-arch-defs@8842ce7.

The above link also contains the build date, so we may probably extract that as well from there.

That is the wrong way around. You want to go from git revision ID to a build result (not from a build result to a git revision ID).
