Hello Again Everyone!
**Note:** This series depends on the OF_UPSTREAM work from Sumit [0]. Patch #11 was added to fix some Makefile.spl targets to allow SPL builds to complete with the OF_UPSTREAM series.
The AM62Px is an extension of the existing Sitara AM62x low-cost family of application processors built for Automotive and Linux Application development. Scalable Arm Cortex-A53 performance and embedded features, such as: multi high-definition display support, 3D-graphics acceleration, 4K video acceleration, and extensive peripherals make the AM62Px well-suited for a broad range of automation and industrial application, including automotive digital instrumentation, automotive displays, industrial HMI, and more.
Some highlights of AM62P SoC are:
* Quad-Cortex-A53s (running up to 1.4GHz) in a single cluster. Dual/Single core variants are provided in the same package to allow HW compatible designs.
* One Device manager Cortex-R5F for system power and resource management, and one Cortex-R5F for Functional Safety or general-purpose usage.
* One 3D GPU up to 50 GLFOPS
* H.264/H.265 Video Encode/Decode.
* Display support: 3x display support over OLDI/LVDS (1x OLDI-DL, 1x or 2x OLDI-SL), DSI, or DPI. Up to 3840x1080 @ 60fps resolution
* Integrated Giga-bit Ethernet switch supporting up to a total of two external ports (TSN capable).
* 9xUARTs, 5xSPI, 6xI2C, 2xUSB2, 3xCAN-FD, 3xMMC and SD, GPMC for NAND/FPGA connection, OSPI memory controller, 3xMcASP for audio, 1xCSI-RX-4L for Camera, eCAP/eQEP, ePWM, among other peripherals.
* Dedicated Centralized Hardware Security Module with support for secure boot, debug security and crypto acceleration and trusted execution environment.
* One 32-bit DDR Subsystem that supports LPDDR4, DDR4 memory types.
* Multiple low power modes support, ex: Deep sleep, Standby, MCU-only, enabling battery powered system design.
For those interested, more details about this SoC can be found in the Technical Reference Manual here: https://www.ti.com/lit/pdf/spruj83

Currently, while more peripherals are being added in Linux[0], this series will only support UART boot.
Thanks for reviewing! ~Bryan
Changes from v1: [1] - squashed all clk and lpsc tree updates into a single commit - corrected SOC_K3_AM642 typo with DM firmware Kconfig option - updated RM configs and dma nodes to enable IP that need DMA - added the dtb targets to the dts/Makefile - rebased the series on top of v2024.01-rc1 - switched to bootstd rather than use distro boot scripts. - enabled OF_UPSTREAM instead of using the arch/arm/dts directory
