Question regarding U-boot MultiCore SMP

[Jan Reinhard]

Hello,


I am working on the PolarFire RISC-V icicle kit and use u-boot to start 
my application.
I configured the firmware to start u-boot on all harts (cores) and found 
out that u-boot uses a "HART lottery system" to decide which core/hart 
it runs on.
In my special case I want u-boot to start on the first hart and the 
other harts shall wait for the interrupt.

I cannot use the "saveenv" but I compile the u-boot myself. Is there a 
way to compile the u-boot to ignore the "HART lottery system" and use 
the first hart?

Thank you in advance.


Regards,
