The current recommendation for best security practice from the US government
is to use SHA384 for TOP SECRET [1].
This patch adds support for SHA384 and SHA512 in the hash command, and also
allows FIT images to be hashed with these algorithms, and signed with
sha384,rsaXXXX and sha512,rsaXXXX
The SHA implementation is adapted from the linux kernel implementation.

The Linux ramdisk should always be decompressed by the kernel itself,
not by U-Boot. Therefore, the 'compression' node in the FIT image should
always be set to "none" for ramdisk images, since the only point of
using that node is if you want U-Boot to do the decompression itself.
Yet some systems populate the node to the compression algorithm used by
the kernel instead. This used to be ignored, but now that we support
decompression of all image types it becomes a problem. Since ramdisks
should never be decompressed by U-Boot anyway, this patch adds a special
exception for them to avoid these issues. Still, setting the
'compression' node like that is wrong in the first place, so we still
want to print out a warning so that third-party distributions doing this
can notice and fix it.

This patch adds support for an optional optimization to compatible
string matching where the compatible string property from the root node
of the kernel FDT can be copied into the configuration node of the FIT
image. This is most useful when using compressed FDTs or when using FDT
overlays, where the traditional extraction of the compatible string from
the kernel FDT itself is not easily possible.

This patch adds support for compressing non-kernel image nodes in a FIT
image (kernel nodes could already be compressed previously). This can
reduce the size of FIT images and therefore improve boot times
(especially when an image bundles many different kernel FDTs). The
images will automatically be decompressed on load.
This patch does not support extracting compatible strings from
compressed FDTs, so it's not very helpful in conjunction with
CONFIG_FIT_BEST_MATCH yet, but it can already be used in environments
that select the configuration to load explicitly.

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.

After an image is selected out of a FIT blob for further processing we
run an optional, platform specific, post-processing function on this
component. This post-processing may modify the position and size of the
image, so after post-processing we update the location and size for this
image in the FIT header. This can cause problems as the position of
subsequent components in the FIT blob are only referenced by relative
position to the end of the last component. When we resize or move a
component the following components position will be calculated
incorrectly. To fix this, we do not update the FIT header but instead
only update our local understanding of the image data. This also allows
us to re-run post-processing steps if needed.

Commit bac17b78dace ("image-fit: switch ENOLINK to ENOENT") changed
fit_get_node_from_config to return -ENOENT when a property doesn't
exist, but didn't change any of its callers which check return values.
Notably it didn't change boot_get_ramdisk, which leads to U-Boot failing
to boot FIT images which don't include ramdisks with the following
message:
Ramdisk image is corrupt or invalid
It also didn't take into account that by returning -ENOENT to denote the
lack of a property we lost the ability to determine from the return
value of fit_get_node_from_config whether it was the property or the
configuration node that was missing, which may potentially lead callers
to accept invalid FIT images.
Fix this by having fit_get_node_from_config return -EINVAL when the
configuration node isn't found and -ENOENT when the property isn't
found, which seems to make semantic sense. Callers that previously
checked for -ENOLINK are adjusted to check for -ENOENT, which fixes the
breakage introduced by commit bac17b78dace ("image-fit: switch ENOLINK
to ENOENT").
The only other user of the return fit_get_node_from_config return value,
indirectly, is bootm_find_os which already checked for -ENOENT. From a
read-through of the code I suspect it ought to have been checking for
-ENOLINK prior to bac17b78dace ("image-fit: switch ENOLINK to ENOENT")
anyway, which would make it right after this patch, but this would be
good to get verified by someone who knows this x86 code or is able to
test it.

In certain circumstances it comes in handy to be able to boot into a second
U-Boot. But as of now it is not possible to boot a U-Boot binary that is inside
a FIT image, which is problematic for projects that e.g. need to guarantee a
unbroken chain of trust from SOC all the way into the OS, since the FIT signing
mechanism cannot be used.
This patch adds the capability to load such FIT images.
An example .its snippet (utilizing signature verification) might look
like the following:
images {
firmware@1 {
description = "2nd stage U-Boot image";
data = /incbin/("u-boot-dtb.img.gz");
type = "firmware";
