Created NanoPi R2S (Rockchip rk3328) 16MB image. Next: boot from SPI flash

Hi @rop I am also trying to boot openwrt on 16MB SPI Flash

I modified Makefile to fit Openwrt image on to SPI
with this changes i builded openwrt and resulting image is now 5.9MB
SPI Flash sysupgrade image support

for adding SPI node to DTB i copied SPI nodes from Orangepi R1 's SPI Flash Supported DTB
https://github.com/melsem/openwrt-19.07.7-spi/raw/master/sun8i-h2-plus-orangepi-r1-dtb
so SPI flash worked with this parts.(I don't know if this partitioning valid for R1 plus )
I am stucked this step and don't know how to implement uboot .

Any help would be appreciated
