aa75ce95ed binman: test: Rename 172_fit_fdt.dts to 170_fit_fdt.dts
Currently there are 2 binman test cases using the same 172 number.
It seems that 172_fit_fdt.dts was originally named as 170_, but
commit c0f1ebe9c1 ("binman: Allow selecting default FIT configuration")
changed its name to 172_ for no reason. Let's change it back.

0fe44dc676 binman: Correct testSplNoDtb() and Tpl also
These two tests require an ELF image so that symbol information can be

having set it up first, but every test must run independently. This can
cause occasional errors in CI.

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.

939d1062d0 binman: Support reading an image with entry args
Normally when an entry is created, any entry arguments it has are required
to be provided, so it can actually generate its contents correctly.

However when an existing image is read, Entry objects are created for each
of the entries in the image. This happens as part of the process of
reading the image into binman.

In this case we don't need the entry arguments, since we do not intend to
regenerate the entries, or at least not unless requested. So there is no
sense in reporting an error for missing entry arguments.

Add a new property for the Image to handle this case. Update the error
reporting to be conditional on this property.

0ff83da634 binman: Use the actual contents in CheckSize()
At present this function adds up the total size of entries to work out the
size of a section's contents. With compression this is no-longer enough.

We may as well bite the bullet and build the section contents instead.
Call _BuildSectionData() to get the (possibly compressed) contents and
GetPaddedData() to get the same but with padding added.

Note that this is inefficient since the section contents is calculated
twice. Future work will improve this.

This affects testPackOverlapMap() since the error is reported with a
different section size now (enough to hold the contents). Update that at
the same time.

63e7ba6c18 binman: Set section contents in GetData()
Section contents is not set up when ObtainContents() is called, since
packing often changes the layout of the contents. Ensure that the contents
are correctly recorded by making this function regenerate the section. It
is normally only called by the parent section (when packing) or by the
top-level image code, when writing out the image. So the performance
impact is fairly small.

Now that sections have their contents in their 'data' property, update
testSkipAtStartSectionPad() to check it.

7d398bb1c7 binman: Make section padding consistent with other entries
At present padding of sections is inconsistent with other entry types, in
that different pad bytes are used.

When a normal entry is padded by its parent, the parent's pad byte is
used. But for sections, the section's pad byte is used.

Adjust logic to always do this the same way.

Note there is still a special case in entry_Section.GetPaddedData() where
an image is padded with the pad byte of the top-level section. This is
necessary since otherwise there would be no way to set the pad byte of
the image, without adding a top-level section to every image.

fe05701b05 binman: Build FIT image subentries with the section etype
When reading subentries of each image, the FIT entry type directly
concatenates their contents without padding them according to their

properties.

This patch makes sure these properties are respected by offloading this
image-data building to the section etype, where each subnode of the
"images" node is processed as a section. Alignments and offsets are
respective to the beginning of each image. For example, the following
fragment can end up having "u-boot-spl" start at 0x88 within the final
FIT binary, while "u-boot" would then end up starting at e.g. 0x20088.

				type = "kernel";
				arch = "arm64";

					align = <0x10000>;

fdc34368dd binman: Add support for generating a FIT
FIT (Flat Image Tree) is the main image format used by U-Boot. In some
cases scripts are used to create FITs within the U-Boot build system. This
is not ideal for various reasons:

- Each architecture has its own slightly different script
- There are no tests
- Some are written in shell, some in Python

To help address this, add support for FIT generation to binman. This works
by putting the FIT source directly in the binman definition, with the
ability to adjust parameters, etc. The contents of each FIT image come
from sub-entries of the image, as is normal with binman.
