Any Raspberry Pi may use device-tree overlays; it is not restricted to Raspberry Pi 3 and 4. The defconfigs for the Raspberry Pi 3, 4, 400, Zero W, Zero 2 W, Compute Module 4 and 4s use the miniuart-bt dtoverlay to switch the Bluetooth to the mini-UART (ttyS0) and restore UART0 (ttyAMA0) over GPIOs 14 and 15 to enable the serial console (like the Raspberry Pi 1 and 2 that have no Bluetooth)[1][2]. As a consequence, the Raspberry Pi Zero W, Zero 2 W, 400, Compute Module 4 and 4s install the device-tree overlays as well. This rewords the note by adding the three missing hardwares installing the images/rpi-firmware/overlays directory. It rewords the miniuart note at the same time.
