feaeee8b5f test: vboot: add tests for multiple required keys
This patch adds vboot tests to verify the support for multiple
required keys using new required-mode DTB policy.

This patch also fixes existing test where dev
key is assumed to be marked as not required, although
it is marked as required.

Note that this patch re-added sign_fit_norequire().
sign_fit_norequire() was removed as part of the following:
commit b008677daf ("test: vboot: Fix pylint errors").
This patch leverages sign_fit_norequire() to fix the
existing bug.

1b09003202 test: vboot: Parameterise the test
This test is actually made up of five separate tests. Split them out so
that they appear as separate tests.

Unfortunately this restarts U-Boot multiple times which adds about a
second to the already-long vboot test, about 8 seconds total on my
machine. We could add a special 'teardown' test afterwards but if the
tests are executed out of order that would not work.

Changing test_vboot into a class causes it not to be discovered and makes
it different from all other tests.

72239fc85f vboot: Add FIT_SIGNATURE_MAX_SIZE protection
This adds a new config value FIT_SIGNATURE_MAX_SIZE, which controls the
max size of a FIT header's totalsize field. The field is checked before
signature checks are applied to protect from reading past the intended
FIT regions.

This field is not part of the vboot signature so it should be sanity
checked. If the field is corrupted then the structure or string region
reads may have unintended behavior, such as reading from device memory.
A default value of 256MB is set and intended to support most max storage
sizes.

8793631ec1 test/py: vboot: Remove stderr redirect from openssl command
The openssl command specified in test_with_algo() ultimately ends up
being run by RunAndLog::run(), which uses it to construct a Popen object
with the default shell=False. The stderr redirect in the command is
therefore simply passed to openssl as an argument. With at least openssl
1.1.0f this causes openssl, and therefore test_vboot, to fail with:

  genpkey: Use -help for summary.
  Exit code: 1

Any stderr output ought to be captured & stored in the RunAndLog
object's output field and returned from run() via run_and_log() to
test_with_algo() which then ignores it anyway, so we can drop the
shell-like redirection with no ill effects. With this fix test_vboot now
passes for me.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
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.
