[PATCH v3 00/13] Hello Again Everyone!

**Note:**  This series depends on the v6 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

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!

Changes from v2: [2]
 - 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: [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
