Experimental Kintex7 xc7k325 support (alternative)

[unbtorsten]

This is an attempt alternative to #1794. Differences are:

• settings/kintex7_325t.sh defines a different tilegrid
• orphan_int_column fuzzer is disabled for xc7k325t
• configure fuzzers/005-tilegrid/generate_full.py to return if XRAY_IOI3_TILES is empty

This pull request is to determine whether changes pass automatic testing.

Looks like you need to rebase before I can test CI.

Indeed. Sorry about the hold-up. I finally managed the intended rebase.

Please note that this commit has been tested with DSP disabled for Kintex7. DSPs were enabled for all devices in #1816. If this turns out to be an issue for this PR, we could try deactivating the DSPs temporarily.

This is blocked by #1833

@acomodi / @kgugala - Can you get the CI fixed ASAP so this PR can be tested?

[acomodi]

@mithro trying to do that in here #1845. Not sure how to convince kokoro to really use Ubuntu bionic or focal, as xenial does not have support for deadsnakes PPA that has python packages.

One of the other options I see is to move to GitHub custom runners

Are there any updates on the end of CI? Still waiting for this PR (or equivalently #1794) to be confirmed for merge.

@unbtorsten - Can you rebase this onto master so that the GitHub Action CI (which replaces kokoro) runs here?

[mithro]

Actually it looks like the GitHub Action stuff hasn't landed yet (see #1846) and Kokoro is currently borked #1833 -- Gah!?

Done

[unbtorsten]

Is CI still broken? How can we move forward with this?

@unbtorsten They currently are working on getting the license working in the new GitHub actions based workflow
