40c8bdd87e binman: Support splitting an ELF file into multiple nodes
Some boards need to load an ELF file using the 'loadables' property, but
the file has segments at different memory addresses. This means that it
cannot be supplied as a flat binary.

Allow generating a separate node in the FIT for each segment in the ELF,
with a different load address for each.

Also add checks that the fit,xxx directives are valid.

2337eca283 binman: Keep a separate list of entries for fit
The current implementation sets up the FIT entries but then deletes the
'generator' ones so they don't appear in the final image.

This is a bit clumsy. We cannot build the image more than once, since the
generator entries are lost during the first build. Binman requires that
calling BuildSectionData() multiple times returns a valid result each
time.

Keep a separate, private list which includes the generator nodes and use
that where needed, to correct this problem. Ensure that the missing list
includes removed generator entries too.

3817ad4c1c binman: Make fake blobs zero-sized by default
On x86 devices having even a small amount of data can cause an overlap
between regions. For example, bayleybay complains when the intel-vga
region overlaps with u-boot-ucode:

38397d0833 binman: Refactor fit to generate output at the end
At present the fit implementation creates the output tree while
scanning the FIT description. Then it updates the tree later when the
data is known.

This works, but is a bit confusing, since it requires mixing the scanning
code with the generation code, with a fix-up step at the end.

It is actually possible to do this in two phases, one to scan everything
and the other to generate the FIT. Thus the FIT is generated in one pass,
when everything is known.

Update the code accordingly. The only functional change is that the 'data'
property for each node are now last instead of first, which is really a
more natural position. Update the affected test to deal with this.

One wrinkle is that the calculated properties (image-pos, size and offset)
are now added before the FIT is generated. so we must filter these out
when copying properties from the binman description to the FIT.

Most of the change here is splitting out some of the code from the
ReadEntries() implementation into _BuildInput(). So despite the large
diff, most of the code is the same. It is not feasible to split this patch
up, so far as I can tell.

730922205b binman: Update image positions of FIT subentries
Binman keeps track of positions of each entry in the final image, but
currently this data is wrong for things included in FIT entries,
especially since a previous patch makes FIT a subclass of Section and
inherit its implementation.

There are three ways to put data into a FIT image. It can be directly
included as a "data" property, or it can be external to the FIT image
represented by an offset-size pair of properties. This external offset
is either "data-position" from the start of the FIT or "data-offset"
from the end of the FIT, and the size is "data-size" for both. However,
binman doesn't use the "data-offset" method while building FIT entries.

According to the Section docstring, its subclasses should calculate and
set the correct offsets and sizes in SetImagePos() method. Do this for
FIT subentries for the three ways mentioned above, and add tests for the
two ways binman can pack them in.

ee813c86f9 binman: Skip processing "hash" subnodes of FIT subsections
Binman's FIT entry type can have image subentries with "hash" subnodes
intended to be processed by mkimage, but not binman. However, the Entry

hash algorithms that binman doesn't support, but mkimage supports.

Let entries skip processing these "hash" subnodes based on an instance
variable, and set this instance variable for FIT subsections. Also
re-enable processing of calculated and missing properties of FIT entries
which was disabled to mitigate this issue.

4897d331f3 binman: Check missing bintools of Section subclasses
Binman can check for missing binary tools and prints warnings if
anything required for an image is missing. The implementation of this
for the Section entry only checks the subentries, presumably because
Section does not use any binary tools itself. However, this means the

tools.

Make sure missing binary tools are checked for subclasses of the Section
entry type as well, by calling the parent class' implementation in
the relevant Section method.

This unbreaks all read-backs of images that contain generator nodes in

252de6b1f7 binman: Add support for bintools
Binman requires various tools to actually work, such as 'lz4' to compress
data and 'futility' to sign Chrome OS firmware. At present these are
handled in an ad-hoc manner and there is no easy way to find out what
tools are needd to build an image, nor where to obtain them.

Add an implementation of 'bintool', a base class which implements this
functionality. When a bintool is required, it can be requested from this
module, then executed. When the tool is missing, it can provide a way to
obtain it.

Note that this uses Command directly, not the tools.Run() function. This
allows proper handling of missing tools and avoids needing to catch and
re-raise exceptions.

While converting to binman for an imx8mq board, it has been found that
building in the u-boot CI fails. This is because an imx8mq requires an
external binary (signed_hdmi_imx8m.bin). If this file cannot be found
mkimage fails.
To be able to build this board in the u-boot CI a binman option
(--fake-ext-blobs) is introduced that can be switched on via the u-boot
makefile option BINMAN_FAKE_EXT_BLOBS. With that the needed dummy files are
created.

31eefd4380 binman: Support packaging U-Boot for scenarios like OF_BOARD or OF_PRIOR_STAGE
For scenarios like OF_BOARD or OF_PRIOR_STAGE, no device tree blob is
provided in the U-Boot build phase hence the binman node information
is not available. In order to support such use case, a new Kconfig
option BINMAN_STANDALONE_FDT is introduced, to tell the build system
that a device tree blob containing binman node is explicitly required
when using binman to package U-Boot.

631f752de5 binman: Support obtaining section contents immediately
Generally the content of sections is not built until the final assembly
of the image. This is partly to avoid wasting time, since the entries
within sections may change multiple times as binman works through its
various stages. This works quite well since sections exist in a strict
hierarchy, so they can be processed in a depth-first manner.

However the 'collection' entry type does not have this luxury. If it
contains a section within its 'content' list, then it must produce the
section contents, if available. That section is typically a sibling
node, i.e. not part oc the collection's hierarchy.

Add a new 'required' argument to section.GetData() to support this. When
required is True, any referenced sections are immediately built. If this
is not possible (because one of the subentries does not have its data yet)
then an error is produced.

The test for this uses a 'collection' entry type, referencing a section as
its first member. This forces a call to _BuildSectionData() with required
set to False, at first, then True later, when the image is assembled.

5187b80617 binman: Use standard filenames for SPL/TPL devicetree
At present, before any entry expansion is done (such as a 'files' entry
expanding out to individual entries for each file it contains), we check
the binman definition (i.e. '/binman' node) to find out what devicetree
files are used in the images.

This is a pain, since the definition may change during expansion. For
example if there is no u-boot-spl-dtb entry in the definition at the start,
we assume that the SPL devicetree is not used. But if an entry later
expands to include this, then we don't notice.

In fact the flexibility provided by the current approach of checking the
definition is not really useful. We know that we can have SPL and TPL
devicetrees. We know the pathname to each, so we can simply check if the
files are present. If they are present, we can prepare them and update
them regardless of whether they are actually used. If they are not present,
we cannot prepare/update them anyway, i.e. an error will be generated.

Simplify state.Prepare() so it uses a hard-coded list of devicetree files.

Note that state.PrepareFromLoadedData() is left untouched, since in that
case we have a complete definition from the loaded file, but cannot of
course rely on the devicetree files that created it still being present.
So in that case we still check the image defitions.
