+Image creation
+==============
+
+Amlogic doesn't provide sources for the firmware and for tools needed
+to create the bootloader image, so it is necessary to obtain them from
+the git tree published by the board vendor:

+ > export FIPDIR=$PWD/fip
+
+Go back to mainline U-Boot source tree then :
+ > mkdir fip
+
+ > cp $FIPDIR/gxl/bl2.bin fip/
+ > cp $FIPDIR/gxl/acs.bin fip/
+ > cp $FIPDIR/gxl/bl21.bin fip/

+ > cp u-boot.bin fip/bl33.bin
+
+ > $FIPDIR/blx_fix.sh \
+	fip/bl30.bin \
+	fip/zero_tmp \
+	fip/bl30_zero.bin \
+	fip/bl301.bin \
+	fip/bl301_zero.bin \
+	fip/bl30_new.bin \
+	bl30
+
+ > python $FIPDIR/acs_tool.pyc fip/bl2.bin fip/bl2_acs.bin fip/acs.bin 0

+	fip/bl21_zero.bin \
+	fip/bl2_new.bin \
+	bl2
+
+ > $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl30_new.bin
+ > $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl31.img
+ > $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl33.bin

+		--bl30 fip/bl30_new.bin.enc \
+		--bl31 fip/bl31.img.enc \
+		--bl33 fip/bl33.bin.enc
+
+and then write the image to SD with:
+
+ > DEV=/dev/your_sd_device
+ > dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=512 skip=1 seek=1
+ > dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=1 count=444
