The DT spec demands a unit-address of a node name to match the "reg"
property in that node. Newer dtc versions will throw warnings if this is
not the case.
Fix all occurences in the FIT image example files where this was not
observed, to not give bad examples to the reader.Signed-off-by: Andre Przywara

In the source_file_format.txt file we talk about how to construct a
valid FIT image. While it already says to look at the source for the
full list, add kernel_noload to the explicit list of types. This is
arguably the most important type to use as most often we are including a
kernel that will run from wherever it is loaded into memory and execute.This for example, allows you to create a single FIT image for Linux that
can be used on both OMAP and i.MX devices as the kernel will not need to
be moved in memory.Signed-off-by: Tom Rini

So far we were not using the FIT image format to its full potential:
The SPL FIT loader was just loading the first image from the /images
node plus one of the listed DTBs.
Now with the refactored loader code it's easy to load an arbitrary
number of images in addition to the two mentioned above.
As described in the FIT image source file format description, iterate
over all images listed at the "loadables" property in the configuration
node and load every image at its desired location.
This allows to load any kind of images:
- firmware images to execute before U-Boot proper (for instance
ARM Trusted Firmware (ATF))
- firmware images for management processors (SCP, arisc, ...)
- firmware images for devices like WiFi controllers
- bit files for FPGAs
- additional configuration data
- kernels and/or ramdisks
The actual usage of this feature would be platform and/or board specific.Also update the FIT documentation to mention the new SPL feature and
provide an example .its file to demonstrate its features.Signed-off-by: Andre Przywara

Add support for signing with the pkcs11 engine. This allows FIT images
to be signed with keys securely stored on a smartcard, hardware security
module, etc without exposing the keys.Support for other engines can be added in the future by modifying
rsa_engine_get_pub_key() and rsa_engine_get_priv_key() to construct
correct key_id strings.Signed-off-by: George McCollister

To help automate the loading of custom image types we add the ability
to define custom handlers for the loadable section types. When we find
a compatible type while loading a "loadable" image from a FIT image we
run its associated handlers to perform any additional steps needed for
loading this image.Signed-off-by: Andrew F. Davis

When building a FIT with external data (-E), U-Boot proper may require
absolute positioning for executing the external firmware. To acheive this
use the (-p) switch, which will replace the amended 'data-offset' with
'data-position' indicating the absolute position of external data.It is considered an error if the requested absolute position overlaps with the
initial data required for the compact FIT.Signed-off-by: Teddy Reed

One limitation of FIT is that all the data is 'inline' within it, using a
'data' property in each image node. This means that to find out what is in
the FIT it is necessary to scan the entire file. Once loaded it can be
scanned and then the images can be copied to the correct place in memory.In SPL it can take a significant amount of time to copy images around in
memory. Also loading data that does not end up being used is wasteful. It
would be useful if the FIT were small, acting as a directory, with the
actual data stored elsewhere.This allows SPL to load the entire FIT, without the images, then load the
images it wants later.Add a -E option to mkimage to request that it output an 'external' FIT.

Remove the verified boot limitation that only allows a single
RSA public exponent of 65537 (F4). This change allows use with
existing PKI infrastructure and has been tested with HSM-based
PKI.Change the configuration OF tree format to store the RSA public
exponent as a 64 bit integer and implement backward compatibility
for verified boot configuration trees without this extra field.Parameterise vboot_test.sh to test different public exponents.

Add a description of how to implement verified boot using signed FIT images,

and verifies it. Then it corrupts the signature to check that this is
detected.Signed-off-by: Simon Glass

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.
