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.

Fix test failure caused by bad handling of ramdisk

2014-08-28T21:18:48+00:00

Commit e3a5bbce broke the FIT image tests by not loading a ramdisk even if
a load address is provided in the FIT. The rationale was that a load address
of 0 should be considered to mean 'do not load'.

Add a new load operation which supports this feature, so that the ramdisk
will be loaded if a non-zero load address is provided.

image: fix bootm failure for FIT image

2014-08-21T16:01:29+00:00

Commit b3dd64f5d537 "bootm: use genimg_get_kernel_addr()" introduced
a bug for booting FIT image. It's because calling fit_parse_config()
twice will give us wrong value in img_addr.

Add a new function genimg_get_kernel_addr_fit() whichl will always
return fit_uname_config and fit_uname_kernel for CONFIG_FIT.
genimg_get_kernel_addr() will ignore those to parameters.

image: introduce genimg_get_kernel_addr()

2014-08-09T15:18:47+00:00

Kernel address is normally stored as a string argument of bootm or bootz.
This function is taken out from boot_get_kernel() of bootm.c, which can be
reused by others.

fit: make sha256 support optional

sha256 has some beefy memory footprint.
Make it optional for constrained systems.

includes: move openssl headers to include/u-boot

2014-06-19T15:19:04+00:00

commit 18b06652cd "tools: include u-boot version of sha256.h"
unconditionally forced the sha256.h from u-boot to be used
for tools instead of the host version. This is fragile though
as it will also include the host version. Therefore move it
to include/u-boot to join u-boot/md5.h etc which were renamed
for the same reason.

Enhance fit_check_sign to check all images

2014-06-19T15:19:02+00:00

At present this tool only checks the configuration signing. Have it also
look at each of the images in the configuration and confirm that they
verify.

image: Remove the fit_load_image() property parameter

2014-06-19T15:18:59+00:00

This can be obtained by looking up the image type, so is redundant. It is
better to centralise this lookup to avoid errors.

Prevent a buffer overflow in mkimage when signing with SHA256

2014-06-05T21:01:23+00:00

Due to the FIT_MAX_HASH_LEN constant not having been updated
to support SHA256 signatures one will always see a buffer
overflow in fit_image_process_hash when signing images that
use this larger hash.  This is exposed by vboot_test.sh.

bootm: make use of legacy image format configurable

2014-06-05T18:44:56+00:00

make the use of legacy image format configurable through
the config define CONFIG_IMAGE_FORMAT_LEGACY.

When relying on signed FIT images with required signature check
the legacy image format should be disabled. Therefore introduce
this new define and enable legacy image format if CONFIG_FIT_SIGNATURE
is not set. If CONFIG_FIT_SIGNATURE is set disable per default
the legacy image format.
