[PATCH v2] RTEMS Boot Image, tool to create SD card images

[chrisj at rtems.org]

Hi,

These patches add a new command to the rtems-tools called rtems-boot-image.
This tool creates boot images for SD cards on FreeBSD, MacOS and Linux. The
tool lets you boot an RTEMS executable from u-boot from an SD card, or
you can support networking options and have u-boot perform a net boot.

The tool uses a configuration file `rtems-boot.ini` that defines the
boards, commands and formats a board needs. Please update for your
board and send in patches.

V2 patches add more network support with network booting and network loading
of a single FDT. I plan to add overlays once I push these patches to
master.

Please test and report.

Finally,the beaglebone black running libbsd is really neat so a big thanks to
everyone who has been working on this BSP and making it happen.

Thanks
Chris
