Question regarding U-boot MultiCore SMP

I am working on the PolarFire RISC-V icicle kit and use u-boot to start
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.
