# Our config does what "make menuconfig" would do if:
# * Setup openwrt for target x86, subtarget x86_64
# * In Target Images check ext4 and Build GRUB images
# Also add all the kernel modules documented at https://openwrt.org/toh/pcengines/apu2#kernel_modules
# Needed to boot OpenWrt from SD card: https://github.com/pcengines/apu2-documentation/blob/master/docs/debug/openwrt.md

# Our Kernel changes are doing what "make kernel_menuconfig" if:
# * Go into Device Drivers → MMC/SD/SDIO
