Respect SOURCE_DATE_EPOCH when building FIT images.

2016-06-24T21:23:10+00:00

Embedding timestamps in FIT images results in unreproducible builds
for targets that generate a fit image, such as dra7xx_evm.

This patch uses the SOURCE_DATE_EPOCH environment variable, when set,
to use specified value for the date.

Thanks to HW42 for debugging the issue and providing the patch:

mkimage: Add a quiet mode

2016-05-23T15:50:19+00:00

Some build systems want to be quiet unless there is a problem. At present
mkimage displays quite a bit of information when generating a FIT file. Add
a '-q' flag to silence this.

mkimage: Close the file when unable to get its size

2016-03-22T16:16:19+00:00

There is a missing close() on the error path. Add it.

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.

imagetool: replace image registration function by linker_lists feature

2015-01-29T18:38:41+00:00

The registration was introduced in commit f86ed6a8d52c99bb2d17d3cac1647edca0c4399c

This commit also removes all registration functions, and the member "next"
from image_type_params struct

imagetool: make the image_save_datafile() available to all image types

2015-01-29T18:38:41+00:00

Move the image_save_datafile() function from an U-Multi specific file
(default_image.c) to a file common to all image types (image.c). And rename it
to genimg_save_datafile(), to make clear it is useful for any image type.

tools: socfpga: Add socfpga preloader signing to mkimage

2014-10-06T15:38:17+00:00

Like many platforms, the Altera socfpga platform requires that the
preloader be "signed" in a certain way or the built-in boot ROM will
not boot the code.

This change automatically creates an appropriately signed preloader
from an SPL image.

The signed image includes a CRC which must, of course, be generated
with a CRC generator that the SoCFPGA boot ROM agrees with otherwise
the boot ROM will reject the image.

Unfortunately the CRC used in this boot ROM is not the same as the
Adler CRC in lib/crc32.c. Indeed the Adler code is not technically a
CRC but is more correctly described as a checksum.

Thus, the appropriate CRC generator is added to lib/ as crc32_alt.c.
