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&;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!!!
Val

OK thanks.

Next question - does it have full support for imx7d?

Yes, imx7d is well supported in the mainline kernel.

I noticed (as I am attempting to apply patches we use), that /arch/arm/mach-imx/cpuidle-imx7d.c exists in the 5.4.X.imx version we are currently using, but is not present in 5.12. But mach-imx7d.c is.
Will I have to add files (via patches) to fully support imx7d?

cpuidle is supported via PSCI implementation in U-Boot.

I suggest you to use U-Boot mainline too.
