mkimage: Support placing data outside the FIT

2016-03-14T23:18:29+00:00

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.

mkimage: Support adding device tree files to a FIT

2016-03-14T23:18:29+00:00

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.

mkimage: Support automatic creating of a FIT without a .its

2016-03-14T23:18:28+00:00

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.

tools: Add a function to obtain the size of a file

2016-03-14T23:18:27+00:00

This will be used in mkimage when working out the required size of the FIT
based on the files to be placed into it.

mkimage: Allow a FIT to include an image of any type

2016-03-14T23:18:27+00:00

At present FIT images are set up by providing a device tree source file
which is a file with a .its extension. We want to support automatically
creating this file based on the image supplied to mkimage. This means that
even though the final file type is always IH_TYPE_FLATDT, the image inside
may be something else.

mkimage: Allow the original file size to be recorded

2015-09-03T03:28:23+00:00

Allow the image handler to store the original input file size so that it
can reference it later.

mkimage: Set up a file size parameter and keep it updated

2015-07-21T23:39:29+00:00

Some functions called by mkimage would like to know the output file size.
Initially this is the same as the input file size, but it may be affected by
adding headers, etc.

Add this information to the image parameters.

Fix musl build

2015-05-08T21:24:17+00:00

This patch fixes cross-compiling U-Boot tools with the musl C library:
  * including  is needed for ulong
  * defining _GNU_SOURCE is needed for loff_t

Tested for target at91sam9261ek_dataflash_cs3.

tools/imagetool: remove linker script

2015-02-16T17:41:41+00:00

Commit a93648d197df48fa46dd55f925ff70468bd81c71 introduced linker generated
lists for imagetool which is the base for some host tools (mkimage, dumpimage,
et al.).  Unfortunately some host tool chains do not support the used type of
linker scripts. Therefore this commit broke these host-tools for them, namely
FreeBSD and Darwin (OS/X).

This commit tries to fix this. In order to have a clean distinction between host
and embedded code space we need to introduce our own linker generated list
instead of re-using the available linker_lists.h provided functionality.  So we
copy the implementation used in linux kernel script/mod/file2alias.c which has
the very same problem (cause it is a host tool). This code also comes with an
abstraction for Mach-O binary format used in Darwin systems.
