041bca5ba3 Add verified boot information and test
Add a description of how to implement verified boot using signed FIT images,
and a simple test which verifies operation on sandbox.

The test signs a FIT image and verifies it, then signs a FIT configuration
and verifies it. Then it corrupts the signature to check that this is
detected.

4d0985295b image: Add support for signing of FIT configurations
While signing images is useful, it does not provide complete protection
against several types of attack. For example, it it possible to create a
FIT with the same signed images, but with the configuration changed such
that a different one is selected (mix and match attack). It is also possible
to substitute a signed image from an older FIT version into a newer FIT
(roll-back attack).

Add support for signing of FIT configurations using the libfdt's region
support.

Please see doc/uImage.FIT/signature.txt for more information.

56518e7104 image: Support signing of images
Add support for signing images using a new signature node. The process
is handled by fdt_add_verification_data() which now takes parameters to
provide the keys and related information.

d5a64237d5 doc: Fix ramdisk examples in doc/uImage.FIT/multi.its
The ramdisk sections in doc/uImage.FIT/multi.its lack
load address and entry point properties. Using examples
from this file will result in unbootable image, u-boot
will issue the following error messages:

Can't get ramdisk subimage load address!
Ramdisk image is corrupt or invalid

This patch adds missing properties to ramdisk sections.

824d82997f Fix example FIT image source files
The example FIT image source files do not compile with the latest dtc and
mkimage. The following error message is produced:

DTC: dts->dtb  on file "kernel.its"
Error: kernel.its 7:0 - 1:0 syntax error
FATAL ERROR: Unable to parse input tree
./mkimage: Can't read kernel.itb.tmp: Invalid argument

The FIT image source files are missing the "/dts-v1/;" directive at the
beginning of the file. Add the directive to the examples.

4bae90904b Automatic software update from TFTP server
The auto-update feature allows to automatically download software updates
from a TFTP server and store them in Flash memory during boot. Updates are
contained in a FIT file and protected with SHA-1 checksum.

More detailed description can be found in doc/README.update.

9ba2e2c819 Remove support for booting ARTOS images
Pantelis Antoniou stated:
	AFAIK, it is still used but the products using PPC are long gone.
	Nuke it plz (from orbit).

So remove it since it cleans up a usage of env_get_char outside of
the environment code.
