Hi,

To add one more point to the discussion: the /incbin/ syntax is being
used in the new image format of U-Boot (we're using dtc with original
patch by Scott Wood, i.e.,
http://www.nabble.com/-PATCH--Add-support-for-binary-includes.-td15596760.html).

If possible, it would be good to have the original syntax preserved once
the feature is merged into the mainline dtc. BTW: any idea on when this
might happen?

Bartlomiej
