Hi Yaroslav,

I would make this two different devices. One for SD-card flash and one
SPI flash device. Then you would not support sysupgrade between SD-card
and SPI. The initial flashing of the SPI image can be done by just dd
the image to the SPI flash from the SD card image.

I would build the SPI flash image in a similar way for any of the MIPS
deices with SPI NOR flash.

I tried to make the SPI work in OpenWrt on this device some time ago,
but never finished:
