+BTicino Mamoj board:
+===================
+
+Build:
+
+ $ make mrproper
+ $ make imx6dl_mamoj_defconfig
+ $ make
+
+   This will generate the SPL image called SPL and the u-boot-dtb.img.
+
+The following methods can be used for booting Mamoj boards:
+
+1. USB SDP boot
+
+1. USB SDP boot:
+---------------
+
+ - Build imx_usb_loader
+
+    $ git clone git://github.com/boundarydevices/imx_usb_loader.git
+    $ cd imx_usb_loader
+    $ make
+
+ - Build the BSP and copy SPL, u-boot-dtb.img in imx_usb_loader directory
+
+ - Put the board in "Serial Download Mode"
+
+ - Plug-in USB-to-Serial, Open minicom 1152008N1 and USB OTG cables to Host
+
+ - Turn-on board
+
+ - Identify VID/PID using lsusb
+
+    Bus 001 Device 010: ID 15a2:0061 Freescale Semiconductor, Inc. i.MX 6Solo/6DualLite SystemOnChip in RecoveryMode
+
+ - Update the conf files
+
+    imx_usb.conf
