a94a261939 common: env_nand: use get_nand_dev_by_index()
As part of preparation for nand DM conversion the new API has been
introduced to remove direct access to nand_info array. So, use it here
instead of accessing to nand_info array directly.

8c9eaadaaa dm: ofnode: use fdt32_t for DT property value to fix sparse warning
DTB is encoded in big endian.  When we retrieve property values,
we need to use fdt32_to_cpu (aka be32_to_cpu) for endian conversion.
This is a bit error-prone, but sparse is useful to detect endian
mismatch.

We need to use (fdt32_t *) instead of (u32 *) for a pointer of a
property value.  Otherwise sparse warns "cast to restricted __be32".

61e51babdb dm: ofnode: rename ofnode_read_prop() to ofnode_get_property()
This function returns the pointer to the value of a node property.
The current name ofnode_read_prop() is confusing.  Follow the naming
of_get_property() from Linux.

The return type (const u32 *) is wrong.  DT property values can be
strings as well as integers.  This is why of_get_property/fdt_getprop
returns an opaque pointer.

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

The boards were checked with:

		awk '{print $7}' | sort); do
	echo $b;
	fdtgrep -c nvidia,tegra20-uart b/$b/u-boot.dtb |grep okay;

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.
