In /boot directory we can found the following kernel files:

• kernel.img: Kernel For ARMv6 - rpi 1 and rpi zero
• kernel7.img: Kernel For ARMv7 - rpi 2 & 3
• kernel7l.img: Used In rpi 4 but I don't known.
• kernel8.img: I don't known.

Does anyone know what kernel7l.img and kernel8.img are used for?
