Hello Again Everyone!
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

Thanks for reviewing!

Changes from v3: [2]
- rebased on current -next
- moved remove_fwl_configs() inside the 'has rom loaded the sysfw'
check to avoid removing the firewalls when the A53 SPL is executed.
- added the TFA address for the AM62Px to the ATF_LOAD_ADDR Kconfig
- fixed formatting issues with clk and dev auto-generated files
Changes from v2: [1]
- dropped the extra ARCH_K3 not needed for the K3_DM_FW option
- removed the extra &main_pktdma and &main_bcdma nodes already
present in the kernel dtbs
- corrected a few patch fixup errors
- rebased ontop op OF_UPSTREAM v5 [0]
- %s/uboot/U-Boot/g
Changes from v1: [0]
- 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
