+Freescale i.MX28 EVK board
+**************************
+
+This file documents the Buildroot support for the Freescale i.MX28 EVK board.
+
+Read the i.MX28 Evaluation Kit Quick Start Guide [1] for an introduction to the
+board.
+
+Build
+=====
+
+First, configure Buildroot for your i.MX28 EVK board:
+
+  make freescale_imx28evk_defconfig
+
+Build all components:
+
+  make
+
+You will find in ./output/images/ the following files:
+  - imx28-evk.dtb
+  - rootfs.tar
+  - u-boot.sd
+  - zImage
+
+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 and root filesystem as needed.
+
+*** WARNING! The script will destroy all the card content. Use with care! ***
+
+  ./board/freescale/imx28evk/create-boot-sd.sh <your-sd-device>
+
+Boot the i.MX28 EVK board
+=========================
+
+To boot your newly created system (refer to the i.MX28 EVK Quick Start Guide
+[1] for guidance):
+- insert the SD card in the SD Card Socket 0 of the board;
+- verify that your i.MX28 EVK board jumpers and switches are set as mentioned
+  in the i.MX28 EVK Quick Start Guide [1];
+- connect an RS232 UART cable to the Debug UART Port and connect using a
+  terminal emulator at 115200 bps, 8n1;
+- power on the board.
+
+Enjoy!
