Proposal: remove meta-arm-systemready

Hi,

I propose that we remove meta-arm-systemready from the meta-arm repository. There are a number of reasons for this:

1) The tests have been failing in CI for several months, but nobody has root-caused the problem yet, suggesting that maybe it’s not actually used.

This is likely because...

2) It only supports the 2.0 release of the IR-band Architecture Compliance Suite  (ACS) from 2023[1]. The SystemReady specification and tests have changed since then, so there’s isn’t much value in a 2.0 test when the qualification requires 3.0.

This suggests that an upgrade is needed, however…

3) As the ACS compliance testing takes a _very_ long time (the CI runs for 12 hours before being killed), the value of running it _inside_ a Yocto build is very limited.  Instead, separate infrastructure that takes an image and runs the tests on dedicated hardware is more common.

Due to these points, I don’t believe that anyone is using meta-arm-systemready.  I plan on removing it at some point in this release cycle, so it won’t be present in the next meta-arm release.

Any objections?

Cheers,
Ross
