Changes for v4:
- Rebase master
- Used support/scripts/genimage.sh
- Dropped common and used board/engicam
- Update http board link.
- Update genimage.cfg
- Update readme.txt
- Add BR2_TARGET_GENERIC_ISSUE
Changes for v3:
- Rename icore with common, since creating a folder with the name of
  SOM is not make sense, becuase the defconfig is the only change.
- Update readme.txt, post-images.sh, engicam_imx6q_icore_defconfig as per
  above change.
- rebased on master
Changes for v2:
- Created icorem6 family board on engicam
- Added Quad/Dual SOM boards support
- Created well defined readme.tx with referance to board/freescale/imx6q-sabresd/
- s/imx6q_icore_defconfig/engicam_/imx6q_icore_defconfig
- Updated DEVELOPERS file
- Created genimage.cfg with added SPL and u-boot-dtb.img partitions
- Removed Latest source configs and updated with fixed version source for U-Boot, Linux
- Add board link on readme.txt
- Removed BR2_TARGET_ROOTFS_TAR_XZ=y
- Created post-image.sh with referance to board/freescale/imx6q-sabresd/

+*****************************************
+Buildroot for Engicam i.MX6 SOM platforms:
+*****************************************
+
+This file documents the Buildroot support for all Engicam i.MX6 SOM
+platform boards.
+
+i.CoreM6 Quad/Dual SOM Starter kits:
+https://www.engicam.com/vis-prod/101120
+
+This configuration uses U-Boot mainline and kernel mainline.
+
+Build
+=====
+
+First, configure Buildroot for the Engicam i.MX SOM's:
+
+- for i.CoreM6 Quad/Dual:
+
+  make engicam_imx6q_icore_defconfig
+
+Build all components:
+
+  make
+
+You will find the following files in output/images/:
+- for i.CoreM6 Quad/Dual:
+  - imx6q-icore.dtb
+  - rootfs.ext4
+  - rootfs.tar
+  - sdcard.img
+  - SPL
+  - u-boot-dtb.img
+  - 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
+
+Buildroot prepares a bootable "sdcard.img" image in the output/images/
+directory, ready to be dumped on a SD card. Launch the following
+command as root:
+
+  dd if=output/images/sdcard.img of=/dev/<your-sd-device>
+
+*** WARNING! This will destroy all the card content. Use with care! ***
+
+For details about the medium image layout, see the definition in
+board/engicam/genimage.cfg
+
+Boot the i.CoreM6 boards with SD boot:
+=====================================
+
+To boot your newly created system:
+- insert the SD card in the SD slot of the board;
+- connect 3-wire RS232 serial port J28 on board, and connect with other
+  serial end or USB cable(if serial-to-usb converter used) using
+  a terminal emulator at 115200 bps, 8n1;
+- close JM3 for sd boot.
+- power on the board.
+
+Enjoy!
