U-Boot loader for SolidRun Cubox-i and Hummingboard.

Install the u-boot.imx file onto the boot disk using:

  dd if=u-boot.imx of=/dev/whatever bs=1k oseek=1 conv=sync

The U-Boot built by this port expects the first 1MB of the boot media to
be reserved for the U-Boot executable and saved environment.  The u-boot.imx
file begins at an offset of 1K from the start of the boot disk.  The U-Boot
environment area begins at an offset of 512K.

This version is patched so that:
 * ELF and API features are enabled to support ubldr.

The sources for this port were originally obtained from commit e4bc4c3ebe
at https://github.com/SolidRun/u-boot-imx6 which appears to be a highly
modified fork of the stock U-Boot 2013.10 release.  As of this writing,
the changes in this fork have not been rolled back into upstream U-Boot.
