> +Introduction:
> +-------------
> +The AM62D2 SoC belongs to the K3 Multicore SoC architecture with DSP core
> +targeted for applications needing high-performance Digital Signal
> +Processing. It is used in applications like automotive audio systems,
> +professional sound equipment, radar and radio for aerospace, sonar in
> +marine devices, and ultrasound in medical imaging. It also supports
> +precise signal analysis in test and measurement tools.
> +
> +Some highlights of AM62D2 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.
> +* DSP with Matrix Multiplication Accelerator(MMA) (up to 2 TOPS) based on
> +  single core C7x.
> +* 3x Multichannel Audio Serial Ports (McASP) Up to 4/6/16 Serial Data Pins
> +  which can Transmit and Receive Clocks up to 50MHz, with multi-channel I2S
> +  and TDM Audio inputs and outputs.
> +* Integrated Giga-bit Ethernet switch supporting up to a total of two
> +  external ports with TSN capable to enable audio networking features such
> +  as, Ethernet Audio Video Bridging (eAVB) and Dante.
> +* 9xUARTs, 5xSPI, 6xI2C, 2xUSB2, 3xCAN-FD, 3x eMMC and SD, OSPI memory
> +  controller, 1x CSI-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.
> +* Low power mode support: Partial IO support for CAN/GPIO/UART wakeup.
> +
> +This SoC is of part K3 AM62x family, which includes the AM62A and AM62P
> +variants. While the AM62A and AM62D are largely similar, the AM62D is
> +specifically targeted for general-purpose DSP applications, whereas the
> +AM62A focuses on edge AI workloads. A key distinction is that the AM62D
> +does not include multimedia components such as the video encoder/decoder,
> +MJPEG encoder, Vision Processing Accelerator (VPAC) for image signal
> +processing, or the display subsystem. Additionally, the AM62D has a
> +different pin configuration compared to the AM62A, which impacts
> +embedded software development.

If you have to make another spin of this, one small nitpick is to have 
this link be consistent with the 'Platform information' section below.
