These have been fixed in tegra/master by the following commit:

	commit 329b71b234fd2dcc60a1369d411e4b55a8117df9
	Author: Stephen Warren <swarren at nvidia.com>
	Date:   Fri Jun 8 12:28:17 2012 +0000

	    fdt: send all dtc output to stderr

	    Commit 896bbb5 "fdt: avoid bad MAKEALL status" added logic to capture
	    the result code from dtc by echoing $? to stdout and capturing it using
	    $(). However, dtc emits some diagnostics to stderr and some to stdout.
	    The diagnostics send to stdout ended up getting captured via $() rather
	    than being echo'd to the user. This caused those diagnostics to be passed
	    to the exit command, which would then fail with the following cryptic
	    error message:

		/bin/sh: line 1: exit: too many arguments

	    Solve this by redirecting all dtc output to stderr so that $() does not
	    capture it. This allows the user to see the actual error message from dtc.
