+Booting from SPI
+----------------
+
+Use Building steps from "Booting from MMC using U-Boot SPL" section.
+
+Partition the SPI in Linux via mtdblock. (Require to boot the board in
+SD boot mode by enabling MTD block in Linux)
+
+Use prebuilt image from here [1], which support to partition the SPI flash.
