From: Tomasz Maciej Nowak <tmn505@xxxxxxxxx> P2180 modules have WiFi in form of BCM4354 chip, and kernel driver supports this one, so enable it for all users. The necessary calibration file can be obtained from Jetson Linux Archive. nvram.txt file is located in "Driver Package (BSP)" in nv_tegra/l4t_deb_packages/nvidia-l4t-firmware_<version>_arm64.deb archive. The rest of necessary blobs can be obtained from official Linux Firmware repository or (newer ones) from Infineon ifx-linux-firmware repository (look in older releases).
