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.
Thanks for your adoption of OF_UPSTREAM work. As evident from this series, it would be much easier to maintain U-Boot specific DT pieces rather than the full SoC specific DT copy from Linux source tree.
Like all good ideas we should have done this years ago. Thanks for taking up the task of making this easier for us.

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
Proof-of-Life: https://paste.sr.ht/~bryanb/af2ac108a9362549aa326f182e87918d52bf2d71
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
