Devices from the TI K3 family of SoCs like the AM654x contain a Device
Management and Security Controller (SYSFW) that manages the low-level
device control (like clocks, resets etc) for the various hardware
modules present on the SoC. These device control operations are provided
to the host processor OS through a communication protocol called the TI
System Control Interface (TI SCI) protocol.
This patch adds a system reset driver that communicates to the system
controller over the TI SCI protocol for allowing to perform a system-
wide SoC reset.

Some TI Keystone 2 and K3 family of SoCs contain a system controller

This patch adds a power domain driver that communicates to the system

various devices present on the SoC. Various power domain functionalities
are achieved by the means of different TI SCI device operations provided
by the TI SCI framework.
This code is loosely based on the drivers/soc/ti/ti_sci_pm_domains.c

On K3 family SoCs, once the ROM loads image on R5, M3 resets R5 and
expects to start executing from 0x0. In order to handle this ROM
updates the boot vector of R5 such that first 64 bytes of image load
address are mapped to 0x0.
In this case, it is SPL's responsibility to jump to the proper image
location. So, update the PC with address of reset vector(like how
other exception vectors are handled), instead of branching to reset.

Also this sequence for FIT image is completely broken

(Note: For legacy images this is working fine).
even from code I don't think this has ever worked properly
