2017-01-14mkimage: Add support for signing with pkcs11George McCollister
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.

2017-01-02tools: mkimage: add firmware-ivt image type for HAB verificationSven Ebenfeld
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.

Adds -i option that allows specifying a ramdisk file to be added to the FIT image when we are using the automatic FIT mode (no ITS file). This makes adding Depthcharge support to LAVA much more convenient, as no additional configuration files need to be kept around in the machine that dispatches jobs to the boards.

2016-06-24mkimage: fit: spl: Add an optional static offset for external dataTeddy Reed
When building a FIT with external data (-E), U-Boot proper may require absolute positioning for executing the external firmware.

2016-03-14mkimage: Support placing data outside the FITSimon Glass
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.

2016-03-14mkimage: Support adding device tree files to a FITSimon Glass
To make the auto-FIT feature useful we need to be able to provide a list of device tree files on the command line for mkimage to add into the FIT. Add support for this feature. So far there is no support for hashing or verified boot using this method. For those cases, a .its file must still be provided. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-03-14mkimage: Support automatic creating of a FIT without a .itsSimon Glass
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.

2016-03-14mkimage: Allow a FIT to include an image of any typeSimon Glass
At present FIT images are set up by providing a device tree source file which is a file with a .its extension.

2016-02-24Gracefully handle 64-bit signed-extended 32-bit Load addressesWilliam Cohen
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 (++).

2015-12-07mkimage: Fix warning from fix for generating multi and script images againMarek Vasut
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.

In order to avoid duplicating code and keep only one point of modification, the functions, structs and defines useful for "dumpimage" were moved from "mkimage" to a common module called "imagetool". 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: +---------------+ +------| fit_image | +--------------+ +-----------+ | +---------------+ | mkimage |--------> | | <-----+ +--------------+ | | +---------------+ | imagetool | <------------| imximage | +--------------+ | | +---------------+ | dumpimage |--------> | | <-----+ +--------------+ +-----------+ | +---------------+ +------| default_image | +---------------+ register_image_tool() register_image_type() Also, the struct "mkimage_params" was renamed to "image_tool_params" to make clear its general purpose.

2013-06-26mkimage: Add -r option to specify keys that must be verifiedSimon Glass
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.
