Raspberry Pi Zero 3 W and Pi 4 Model A discovered in Linux kernel

Device tree files for two unannounced Raspberry Pi boards, the Zero 3 W and a Pi 4 Model A, have appeared in the Raspberry Pi Linux kernel tree. These files were included via pull request 7711 and signed by Raspberry Pi developer Marta Momotko.

The Zero 3 W appears to feature the Broadcom BCM2711 SoC, which is the same quad-core Cortex-A72 chip used in the Raspberry Pi 4. This represents a significant performance increase over the Zero 2 W, which utilizes a quad-core Cortex-A53. While the device tree mentions an eMMC/SD card storage configuration, it remains unclear if eMMC will be included in the final consumer product due to potential cost implications.

The Pi 4 Model A is also indicated by the new files, with reports suggesting it may lack Ethernet and an audio jack. Additionally, recent kernel commits have addressed GPIO controller updates for the BCM2711, though these changes are not explicitly linked to the new hardware.
