# To enable the SPI NOR the -spi .dtb is required, because eMMC shares a pin with SPI on the N2(+). To use it:
# fdtfile=amlogic/meson-g12b-odroid-n2-plus-spi.dtb # in armbianEnv.txt and reboot, then run nand-sata-install

# Unfortunately it uses n2_plus instead of n2-plus as the Kernel expects it.
#    So there is a hack at and around config/bootscripts/boot-meson64.cmd L90
# If needed (eg for extlinux) you can specify the N2/N2+/ DTB in BOOT_FDT_FILE, example for the N2+:
# BOOT_FDT_FILE="amlogic/meson-g12b-odroid-n2-plus.dtb"
