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.

When we want to use Secure Boot with HAB from SPL over U-Boot.img,
we need to append the IVT to the image and leave space for the CSF.
Images generated as firmware_ivt can directly be signed using the
Freescale code signing tool. For creation of a CSF, mkimage outputs
the correct HAB Blocks for the image.
The changes to the usual firmware image class are quite small,
that is why I implemented that directly into the default_image.

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.

Signed-off-by: Simon Glass <sjg@chromium.org>
At present, when generating a FIT, mkimage requires a .its file containing
the structure of the FIT and referring to the images to be included.
Creating the .its file is a separate step that makes it harder to use FIT.
This is not required for creating legacy images.
Often the FIT is pretty standard, consisting of an OS image, some device
tree files and a single configuration. We can handle this case automatically
and avoid needing a .its file at all.
To start with, support automatically generate the FIT using a new '-f auto'
option. Initially this only supports adding a single image (e.g. a linux
kernel) and a single configuration.

To follow the MIPS 32-bit and 64-bit memory map conventions (*) recent
MIPS Linux kernels are using a 64-bit sign extended value
(0xffffffff80010000) for the 32-bit load address (0x80010000) of the
Creator CI20 board kernel. When this 64-bit argument was passed to
mkimage running on a 32-bit machine such as the Creator CI20 board the
load address was incorrectly formed from the upper 32-bit sign-extend
bits (0xffffffff) by the strtoul instead of from the lower 32-bits
(0x80010000). The mkimage should be able to tolerate the longer
sign-extended 64-bit version of the 32-bit arguments with the use of
strtoull. Use of the strtoll in place of the strtol in mkimage.c
resolves the issue of self hosted kernel builds for the Creator CI20
board (+) and (++).

Seems 6ae6e160 broke creating images in certain cases, there
are two problems with that patch.
First is that the expression "!x == 4 || !x == 6" is ambiguous. The
intention here was "!(x == 4) || !(x == 6)" based on reading further in
the file, where this was borrowed from. This however is interpreted by
gcc as "(!x) == 4 || (!x) == 6" and always false. gcc-5.x will warn
about this case.
The second problem is that we do not want to test for the case of "(NOT x
is 4) OR (NOT x is 6)" but instead "(x is not equal to 4) AND (x is not
equal to 6)". This is because in those two cases we already execute the
code question in another part of the file. Rewrite the expression and
add parenthesis for clarity.

This modification also weakens the coupling between image types (FIT, IMX, MXS,
and so on) and image tools (mkimage and dumpimage). Any tool may initialize the
"imagetool" through register_image_tool() function, while the image types
register themselves within an image tool using the register_image_type()
function:

Normally, multiple public keys can be provided and U-Boot is not
required to use all of them for verification. This is because some
images may not be signed, or may be optionally signed.
But we still need a mechanism to determine when a key must be used.
This feature cannot be implemented in the FIT itself, since anyone
could change it to mark a key as optional. The requirement for
key verification must go in with the public keys, in a place that
is protected from modification.
Add a -r option which tells mkimage to mark all keys that it uses
for signing as 'required'.
If some keys are optional and some are required, run mkimage several
times (perhaps with different key directories if some keys are very
secret) using the -F flag to update an existing FIT.
