Fabio Estevam 98524e573c configs/freescale_imx7dsabresd: Apply upstream U-Boot fix 
NXP U-Boot tree has the following build issue:

  MKIMAGE u-boot-dtb.imx
Error: No BOOT_FROM tag in board/freescale/mx7dsabresd/imximage.cfg.cfgtmp
arch/arm/imx-common/Makefile:91: recipe for target 'u-boot-dtb.imx' failed
make[2]: *** [u-boot-dtb.imx] Error 1
Makefile:877: recipe for target 'u-boot-dtb.imx' failed

This issue has been fixed by commit  f916757300c1  ("imx: Create
distinct pre-processed mkimage config files"), so backport this
commit to the NXP U-Boot tree in order to fix the build error.

Freescale i.MX7D SDB board
***************************

This file documents the Buildroot support for the Freescale i.MX7D SDB board.

Build
=====

First, configure Buildroot for your i.MX7D SDB board:

  make freescale_imx7dsabresd_defconfig

Build all components:

  make

You will find in output/images/ the following files:
  - imx7d-sdb.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.MX7D SDB 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!
