BOOT from SD card

• Best way is to just boot openwrt from your SD card.
• If your EMMC is empty, openwrt will automatically boot from your SD card. (goto uboot console and run store init 3 for erase emmc)
• Else, Uboot will start from EMMC by default - it can boot from SD card, but only with the proper version and config!
