The series adds support for J742S2 family of SoCs. Also adds J742S2 EVM Support and re-uses most of the stuff from the superset device J784s4.
This device is a subset of J784S4 and shares the same memory map and thus the code is being reused from J784S4 to avoid duplication.
It initially cleans up the J784s4 and AM69 files so that they can be re-usable for j742s2 and then it introduces J742S2.
The DT for the following SoC will be coming to U-boot during 6.13 Sync so the series is kept as RFC till then.
Here are some of the salient features of the J742S2 automotive grade application processor:
The J742S2 SoC belongs to the K3 Multicore SoC architecture platform, providing advanced system integration in automotive, ADAS and industrial applications requiring AI at the network edge. This SoC extends the K3 Jacinto 7 family of SoCs with focus on raising performance and integration while providing interfaces, memory architecture and compute performance for multi-sensor, high concurrency applications.
Some changes that this devices has from J784S4 are: * 4x Cortex-A72 vs 8x Cortex-A72 * 3x C7x DSP vs 4x C7x DSP * 4 port ethernet switch vs 8 port ethernet switch * 2 DDR controller vs 4 DDR controller
