+Subject: [PATCH] mx6qsabre_common: boot Linux to /init in mfgtools mode
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Buildroot supplies a nice /init wrapper script to use when booting from a
+ramdisk.
+
+This patch tells u-boot to tell the kernel to boot into /init (instead of
+/linuxrc) on i.MX6, when booting in mfgtools mode. This way we can boot a
+buildroot system entirely through USB.

+*******************************************************
+Freescale i.MX6Q and i.MX6DL SABRESD development boards
+*******************************************************
+
+This file documents the Buildroot support for the Freescale SABRE Board for
+Smart Devices Based on the i.MX 6 Series (SABRESD).
+
+Read the SABRESD Quick Start Guide for an introduction to the board:
+http://cache.freescale.com/files/32bit/doc/quick_start_guide/SABRESDB_IMX6_QSG.pdf
+
+Build
+=====
+
+First, configure Buildroot for your SABRE board.
+For i.MX6Q SABRE SD board:
+
+  make freescale_imx6qsabresd_defconfig
+
+For i.MX6DL SABRE SD board:
+
+  make freescale_imx6dlsabresd_defconfig
+
+Build all components:
+
+  make
+
+You will find in ./output/images/ the following files:
+  - imx6dl-sabresd.dtb or imx6q-sabresd.dtb
+  - rootfs.ext2
+  - rootfs.tar
+  - u-boot.imx
+  - uImage
+
+Create a bootable SD card
+=========================
+
+To determine the device associated to the SD card have a look in the
+/proc/partitions file:
+
+  cat /proc/partitions
+
+Run the following script as root on your SD card. This will partition the card
+and copy the bootloader, kernel, DTBs and root filesystem as needed.
+
+*** WARNING! The script will destroy all the card content. Use with care! ***
+
+  ./board/freescale/create-boot-sd.sh <your-sd-device>
+
+Boot the SABRE board
+====================
+
+SABRE SD
+--------
+
+To boot your newly created system on a SABRE SD Board (refer to the SABRE SD
+Quick Start Guide for guidance):
+- insert the SD card in the SD3 slot of the board;
+- locate the BOOT dip switches (SW6), set dips 2 and 7 to ON, all others to OFF;
+- connect a Micro USB cable to Debug Port and connect using a terminal emulator
+  at 115200 bps, 8n1;
+- power on the board.
+
+Enjoy!
