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 at 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
