-**************************
-Freescale i.MX25 PDK board
-**************************
-
-This file documents the Buildroot support for the Freescale i.MX25 PDK board.
-
-Build
-=====
-
-First, configure Buildroot for the i.MX25 PDK board:
-
-  make mx25pdk_defconfig
-
-Build all components:
-
-  make
-
-You will find in output/images/ the following files:
-  - imx25-pdk.dtb
-  - rootfs.ext4
-  - rootfs.tar
-  - sdcard.img
-  - u-boot.imx
-  - 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
-
-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/freescale/common/imx/genimage.cfg.template.
-
-Boot the i.MX25 PDK board
-=========================
-
-To boot your newly created system:
-- insert the SD card in the SD slot of the board;
-- put a USB cable into the Debug USB Port and connect using a terminal
-  emulator at 115200 bps, 8n1;
-- power on the board.
-
-Enjoy!
