Hi Kever,
As per Rockchip RK3399 TRM V1.4 Part1 RK3399 have
dual-core Cortex-A72 and a quad-core Cortex-A53 +
Cortex-M0 for power management firmware.
So can this feature be enabled for all RK3399 SBC.
or is this meant for specific RK3399 family of processor.
-Anand

U-Boot use the default primary core which is power on enabled Cortex-A53 0,
and other Cortex-A53 and Cortex-A72 are bring up by kernel SMP driver.
For Cortex-M0, it's used in ATF for power management, so I don't think they
have anything to do with U-Boot now.

What do you mean "be enabled"? I think they already enabled...

It's for all RK3399 SBC.
