How to do a SW reset for A72

I am using LS1046A[A72] processor, I wanted to do a software reset. Is writing to RMR_EL3 the only way to trigger SW reset.

It is an EL3 register u-boot leaves in EL2, so I can not set this register.

Is there any alternate way to perform the SW reset.

Look at the Section 4.4.3 of the LS1046A Reference Manual Rev 1:

This Section contains command sequence for core soft reset.


Have a great day,
