2020-04-24mkimage: fit_image: Add option to make fit header alignKever Yang
The image is usually stored in block device like emmc, SD card, make the offset of image data aligned to block(512 byte) can avoid data copy during boot process. eg. SPL boot from FIT image with external data: - SPL read the first block of FIT image, and then parse the header; - SPL read image data separately; - The first image offset is the base_offset which is the header size; - The second image offset is just after the first image; - If the offset of imge does not aligned, SPL will do memcpy; The header size is a ramdon number, which is very possible not aligned, so add '-B size'to specify the align size in hex for better performance. example usage: ./tools/mkimage -E -f u-boot.its -B 0x200 u-boot.itb Signed-off-by: Kever Yang <kever.yang@rock-chips.com> Reviewed-by: Punit Agrawal <punit1.agrawal@toshiba.co.jp> Reviewed-by: Tom Rini <trini@konsulko.com>

2020-04-17mkimage: fit: don't create image with 0700 permissionsThomas Hebb
commit 7298e422504e ("mkimage: fit: add support to encrypt image with aes") added a new copyfile() function as part of the FIT image creation flow. This function as currently written creates the final image with a mode of 0700 (before umask), differing from the old behavior of 0666. Since there doesn't seem to be any reason to make the image executable or non-group, non-other readable, change the mask to 0666 to preserve the old behavior.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

2016-03-14mkimage: Bring data into the FIT before processingSimon Glass

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 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.

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.
