This was unnoticed regression for mvpp2 +  ACPI. I found a root cause and
(unintentional) fix and asked stable for backporting:
https://www.spinics.net/lists/netdev/msg690904.html
Fedora 32 with DT works smoothely though.

Regarding other distros:
- Debian works fine (with DT)
- Centos 8.2 installs and works. Unfortunately they did not include mvpp2
module, I need to reach out to the distro maintainers to add it back into
config.
- FreeBSD works fine with ACPI. With DT there are more interfaces
available, but for that we'd need to use the latest DT from Linux. After
the switch Debian stops working  (broken backward compat in bindings around
interrupts), so I decided to keep the older one for now.

You can try one of my latest builds:
https://drive.google.com/file/d/1FR5cVum7o2w8Ug1cjBSznJCeCIkhrI5R/view?usp=sharing

- I managed to instal the VMware ESXI.
The ESXI itself had a bug (after my report fix for it will be in the next
release - I was told it's a matter of days). If you want to play with it
now, you can try an image with a hack in SPCR description:
https://drive.google.com/file/d/1c-gE5GBKs7e5slO7vV7sva1X6SJtSWBJ/view?usp=sharing

- I tried to install ubuntu 20.04, but for some reason at the end of the
install process it terminates without setting the proper efi boot
partition. I did not debug it.

Best regards,
Marcin
