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
