This is an almost identical copy of the am62x_m4. Should I keep this Copyright or change it?

@dnltz There is no need to retain the copyright in this particular case. However we need some strategy to not duplicate these SoC level dtsi files (atleast for different cores in same SoC), in this case it is okay.

the original file size is 1.5MB and this link only saves 135kB. I already resized the original PNG to 30% before converting it to wepb. I think 100kB are allowed for pictures.

It would be nice to provide instructions to do the same from u-boot console, that provides a faster development environment. I do something like below for development on m4/a53 on AM62 SK
dhcp; setenv serverip 192.168.0.108; rproc init; rproc stop 0; tftp
0x82000000 zephyr.elf; rproc load 0 0x82000000 $filesize; rproc start
0;tftp 0x82000000 zephyr.bin; dcache flush; icache flush; dcache off;
icache off; go 0x82000000

Thanks for sharing those commands with me! We currently figuring out how to improve Zephyr/MCU+ integration into our products and they will be very helpful.
I will update documentation for both products later. Kinda thinking this might be a nice uboot environment function...

The AM64x and AM62x are both SOCs from the TI K3 family and share common architecture designs. The M4F subsystem is actuall identical on both SOCs. Therefore, just add all missing CONFIGs, files, etc. to support the AM6442x SOC. Since MMR and RAT initialization are identical too, both functions can be re-used. However, since they might differ in the future, the am64x has it's own init function. Signed-off-by: Daniel Schultz <d.schultz@phytec.de>
We define two frequencies in the am62x_m4.dtsi file. Use DT_FREQ_M for both frequency to make them more human-readable and easier to understand. Signed-off-by: Daniel Schultz <d.schultz@phytec.de>
This file is basically a copy of the AM62x M4 dtsi but an additional mcu_uart1 interface. The internal clock frequency feeded into the UART IP is 96 MHz instead of 48 MHz, which is different to the AM62x. Signed-off-by: Daniel Schultz <d.schultz@phytec.de>
Add PHYTEC's phyBOARD-Electra kit with the phyCORE-AM64x System on Module (SOM). This board only supports the M4F core, UART and GPIO right now, since other drivers are still missing. Signed-off-by: Daniel Schultz <d.schultz@phytec.de>
An address-cells definition is not required for the gpio node and therefore should be removed. Signed-off-by: Daniel Schultz <d.schultz@phytec.de>

@gramsay0 had to rebase due a conflict in the MAINTAINERS.yml file. |
Add support for TI's AM6442 SOC, which is almost identical to the AM62x. Moreover, it adds support for the phyBOARD-Electra kit, which includes the phyCORE-AM64x SOM.
This PR uses the same board names as introduced in #70913
