Is the following a recommended upstream u-boot?

u-boot-v2021.04 from
https://nam02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fsource.denx.de%2Fu-boot%2Fu-boot%2F&amp;data=04%7C01%7Cvaleriy.kondratenko%40jci.com%7C9d81ccfd81c14c0c3f5c08d93806c619%7Ca1f1e2147ded45b681a19e8ae3459641%7C0%7C0%7C637602424008919863%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&amp;sdata=W7VRDmOAXNwxGNXX4kRgOvSij%2BOFq6k5I%2Fy%2FaBVnpiA%3D&amp;reserved=0

The cpuidle functionality would be in?

arch/arm/mach-imx/mx7/psci-mx7.c

From when/which release U-boot started support cpuidle?

Is there any documentation on how to move the cpuidle functionality from kernel to u-boot?
What is involved there?

Thanks in advance,
 Val

One other thing I see missing in 5.12, that was in freeescale 5.4, is the rpmsg (Remote Processor Messaging) functionality.

Thanks again!!!

Yes, imx7d is well supported in the mainline kernel.

cpuidle is supported via PSCI implementation in U-Boot.

I suggest you to use U-Boot mainline too.
