Only the following devices/functionalities were added:
 * Main UART and the memory node information.
 * NAND.
 * Ethernet.
 * i2c and its pcf8563 device.
 * The GPIO button (its label is BP1 on the baseboard).
 * The GPIO backlight.
 * The GPIO LCD enabling/disabling.
 * Display/IPU controller.
 * Touchscreen.

Hi Denis,

The fsl.txt file contains boards that are developed by Freescale.

The compatible string "fsl,eukrea_cpuimx51" is not correct, as the
cpuimx51 board is not manufactured by Freescale.

You should have used "eukrea" as the manufacturer instead.
