configs: new configuration for NXP i.MX51 EVK
Add a new configuration for NXP i.MX51 EVK based on U-boot 2016.05 and kernel 4.6.1. U-boot 2016.05 needs the patch c510f2e436008 ("video: ipu_common: fix build error") that is already in mainline to fix an IPU build error. We can remove this patch in the future when we switch to U-boot 2016.07. Signed-off-by: Fabio Estevam <festevam@gmail.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

+**************************
+Freescale i.MX51 EVK board
+**************************
+
+This file documents the Buildroot support for the Freescale i.MX51 EVK board.
+
+Build
+=====
+
+First, configure Buildroot for the i.MX51 EVK board:
+
+ make mx51evk_defconfig
+
+Build all components:
+
+ make
+
+You will find in output/images/ the following files:
+ - imx51-babbage.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/imx51evk/genimage.cfg.
+
+Boot the i.MX51 EVK board
+=========================
+
+To boot your newly created system:
+- insert the SD card in the SD slot of the board;
+- put a micro USB cable into the Debug USB Port and connect using a terminal
+ emulator at 115200 bps, 8n1;
+- power on the board.
+
+Enjoy!
