# To enable the SPI NOR, the -spi .dtb is required, because eMMC shares a pin with SPI on the REF board.
# To use SPI:
#   fdtfile=amlogic/s6_s905d5_bq201_linux-spinor.dtb in armbianEnv.txt and reboot, then run armbian-install
# After deploying to SPI-NOR/MTD, return back to the normal DTB, otherwise eMMC speed is impaired.
