 It uses default kernel config (`make bcmrpi_defconfig`), as recommended by the [official documentation](https://www.raspberrypi.com/documentation/computers/linux_kernel.html#cross-compiling-the-kernel), with the addition of the SquashFS module (`CONFIG_SQUASHFS`, which is required for gokrazy) and `CONFIG_IPV6`.
 
+Further additions include the `CONFIG_W1`, `W1_MASTER_GPIO`, `W1_SLAVE_THERM` and `GPIOLIB`.
