f53dcc0e35 tegra: fdt: Ensure that the console UART is enabled
Many tegra boards have the console UART node disabled. With livetree this
prevents serial from working since it does not 'force' the console to be
bound. Updates the affected boards to fix this error.

The boards were checked with:

for b in $(grep  tegra boards.cfg  |grep -v integrator | \
		awk '{print $7}' | sort); do
	echo $b;
	fdtgrep -c nvidia,tegra20-uart b/$b/u-boot.dtb |grep okay;
done

additions need not be considered further.

2ddd85dc34 moveconfig: Allow piping in 'git show --stat' output
It is useful to be able to process only a subset of boards to save time.
Often that subset is defined by the defconfig files in a git commit. This
change allows things like:

   # Build the database
   ./tools.moveconfig.py -b

   # Find some implying configs
   ./tools/moveconfig.py -i CONFIG_X

   # Add some 'imply' statements to Kconfig files
   ./tools/moveconfig.py -i CONFIG_X -a CONFIG_A,CONFIG_B

   # Reprocess the defconfig files to see if we can drop some changes
   git show --stat | ./tools/moveconfig.py -s -d -

   # Update the commit, with fewer defconfig changes
   gii commit -au

Where the commit contains defconfig files, this will reprocess them to
take account of the imply statements that you added.
