What tests have you run with ACPI on MinnowMax? And any errors did you see?

I am getting PCI configuration errors on Minnowmax similar to those we have on QEMU. I am trying to solve them.
What tests have you run with ACPI on MinnowMax?
I am fixing the errors first before going into testing. The first step is to let Linux parse the ACPI table without any errors. Then we can go into the testing aspect for different power stages.

I'm interested in ACPI support for BayTrail (e.g. MinnowMAX). And noticed that you didn't follow up on this MinnowMAX ACPI support thread. In another patchset by Miao (added to Cc), ACPI support has now been added for QEMU already:
https://www.mail-archive.com/u-boot@lists.denx.de/msg200312.html
So what is the current status of ACPI for x86 in U-Boot? Is someone currently working on BayTrail / MinnowMAX ACPI support? If yes, please let me know so that we can combine our efforts. If not, please give me some hints on how to best start / continue here. Why did this patchset from Saket not make it into mainline? What are the main flaws / problems?
Any hints or suggestions welcome! :)
Thanks, Stefan

So far the only working ACPI support for x86 in U-Boot is QEMU, with fw_cfg.
currently working on BayTrail / MinnowMAX ACPI support? If yes, please let me know so that we can combine our efforts. If not, please give me some hints on how to best start / continue here. Why did this patchset from Saket not make it into mainline? What are the main flaws / problems?
Saket's patch does not get ACPI fully working on MinnowMAX. And I guess he has stopped working on this, Simon?
Any hints or suggestions welcome! :)
To support ACPI on real boards, the main task is to write ASL files to describe the on-board devices, using AML language. We can take most of these from coreboot though. The other part is to program these ACPI registers as required by the spec.
