tle: ppc64 is POWER8+ only, no PPC970/ PA6T?
Only POWER ISA 2.7+ and Little Endian only at this stage. I do plan to support Big Endian but the amount of work would be triple (POWER8, POWER9 and POWER10 fast paths all need to be carefully revised and tested).
I wish I could offer support for PPC970/PA6T but lacking of real hardware would make it very hard for me to pick up many issues.
I have a PowerMac G5 with Debian (and also an X1000 but haven't try Linux on it for years). I have very few time and I have no experience with the topic but if it helps to build and test some things, you're welcome.
A comment about your initial message though: you asked to people for a review of your pull request but to me, as a human, it is not possible to review such big pull request.
