The AM62D2 SoC, part of the K3 architecture, is built for high-performance
DSP tasks in automotive audio, pro audio, radar, sonar, and medical
imaging. It features up to four Cortex-A53 cores (1.4GHz), two Cortex-R5F
cores, and a C7x DSP with 2 TOPS MMA. Key interfaces include multi-channel
McASP audio, TSN-capable Gigabit Ethernet, and a range of peripherals
(UART, SPI, I2C, CAN, USB, eMMC/SD, OSPI, CSI). It supports LPDDR4/DDR4,
secure boot with hardware security, and low-power modes with
CAN/GPIO/UART wakeup.

This isn't architecture and board, it's just a board, it should be a
single patch. In that some of these yaml files are big, it would be good
to figure out as a generic problem how to reduce that if possible (I
don't know if it is).
Thanks for the review. Will take into account in the next revision.
In case of am62d, I could reuse the same yaml file as am62a. That should
reduce the patch size at-least.
For a generic solution across boards, we need to have a right usage
model something that will need more discussion. Same with the case of
ddr config here.
