> * This is similar to the symlinks provided for the kernel image
>   in the /boot directory of a file system.  The goal is to have
>   simply named symlinks in /boot that mirror the device tree
>   name in the kernel sources.  This is so that programs like
>   U-Boot can easily find the default device tree binary in the
>   /boot directory and use that when booting the kernel.
> * Use update-alternatives to handle proper creation and removal
>   of the symlinks.
> * This patch has already been accepted into the master branch

> * Updated in version 2
>     * Changed the variable names to use variables that match the
>       do_install and do_deploy more closely for consistency.
> i.e.
>       using DTB_SYMLINK_NAME instead of DTB_NAME.
>     * The above changes were based on input from:
