This directory contains firmware/microcode needed for peripherals in some Librem boards, for OSes that do not provide device firmware.
When the blob jail feature is enabled, PureBoot provides device firmware to the OS by adding it to the initrd, then copying it to /run/firmware (see initrd/bin/inject_firmware.sh).
## Librem Mini v2
Librem Mini v2 ships with an Atheros Wi-Fi/Bluetooth card, which does not require firmware for Wi-Fi (but it does for Bluetooth). However, some whitelabel variants ship with Intel AX200, which requires firmware for both Wi-Fi and Bluetooth.
