This tool always verifies the default configuration. It is useful to be
able to verify a specific one. Add a command-line flag for this and plumb
the logic through.

Add an option to open files in read-only mode in mmap_fdt so
that fit_check_sign can be used to inspect files on read-only
filesystems.
For example, this is useful when a key is shipped in a read-only
rootfs or squashfs.

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.

In the "Getting Started with Coccinelle - KVM edition" presentation that
has been held by Julia Lawall at the KVM forum 2015 (see the slides at
http://events.linuxfoundation.org/sites/events/files/slides/tutorial_kvm_0.pdf),
she pointed out some bad return value checks in U-Boot that can be
detected with Coccinelle by using the following config file:
@@
identifier x,y;
identifier f;
statement S;
@@
x = f(...);
(
if (x < 0) S
|
if (
- y
+ x
< 0) S
)
This patch now fixes these issues.

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.

It is more common to have 0 mean OK, and -ve mean error. Change this
function to work the same way to avoid confusion.

These tools crash if no arguments are provided. Add checks to avoid this.

When adding hashes or signatures, the target FDT may be full. Detect this
and automatically try again after making 1KB of space.

Make the error handling common, and make sure the file is always closed
on error. Rename the parameter to be more description and add comments.

It is trivial to crash fit_check_sign by invoking with an
absolute path in a deeply nested directory. This is exposed
by vboot_test.sh.

add host tool "fit_check_sign" which verifies, if a fit image is
signed correct.
