+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
+      0x15a2:0x0061, mx6_usb_rom.conf, 0x0525:0xb4a4, mx6_usb_sdp_spl.conf
+
+    mx6_usb_rom.conf
+      mx6_usb
+      hid,1024,0x910000,0x10000000,512M,0x00900000,0x40000

+      u-boot-dtb.img:jump header2
+
+  - Launch the loader
+
+     $ ./imx_usb
+
+  We can see U-Boot boot from USB SDP on minicom
