flash to sdcard
dd if=u-boot-sunxi-with-spl.bin of=/dev/sdc bs=8k seek=1
boot and check sf probe and dm tree
=> sf probe
Warning: SPI speed fallback to 100 kHz

flash to SPI
first write the image to sdcard
xzcat u-boot-sopine-flash-spi.img.xz | sudo dd of=/dev/sdc
then boot from the sdcard and it will automatically flash the SPI. After a couple of minutes you can poweroff, remove the sdcard and the sopine will boot from SPI and try to load the kernel from the location provided via DHCP
