Kernel image:
(under linux source directory: /arch/arm64/boot/)

• Image : linux kernel binary

Device tree blobs:
(under linux source directory: /arch/arm64/boot/dts/freescale/)

• imx8mq-pico-pi.dtb : device tree file for HDMI output
• imx8mq-pico-pi-dcss-ili9881c.dtb : device tree file for MIPI-DSI panel(ili9881) output
• imx8mq-pico-pi-m4.dtb : device tree file with enabled cortex-m4
