Sometimes it is useful to specify the default alignment for all entries
in a section, such as when word-alignment is necessary, for example. It
is tedious and error-prone to specify this individually for each section.
Add a property to control this for a section.

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.

The vblock entry type includes code to collect the data from a number of
other entries (not necessarily subentries) and concatenating it. This is
a useful feature for other entry types.
Make it a base class, so that vblock can use it, along with other entry
types.

At present there is a command-line flag to disable substitution of expanded

When creating an entry, check for an expanded version of that entry, then
use it instead. This allows, for example use of:
u-boot {
};
instead of having to write out in full:
u-boot {

u-boot-nodtb {
};
u-boot-dtb {
};
};

As the first step in supporting expanded entries, add a way for binman to
automatically select an 'expanded' version of an entry type, if requested.
This is controlled by a class method.
Signed-off-by: Simon Glass <sjg@chromium.org>
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.

At present we store an entry as the third field in output_fdt_info[].
This is only used to get the type of the entry. Of course multiple entries
may have this same type. Also the entry type is the key to this dict, so
we can use that instead.
Drop the field and update GetUpdateNodes() to suit. Improve the comment for
output_fdt_info a little while here.

At present we always use the main devicetree for SPL/TPL as well when
setting up the state. But this it not needed if there is a real devicetree
for SPL or TPL. In fact it confuses things since we cannot distinguish
between one being provided and using the fake one.
Update the code to create the fakes only when requested. Put the mapping
in a constant so we can use it elsewhere.
Rename 'other_fname' to 'fname' while we are here since there is nothing
'other' about it.

At present if a devicetree blob is included in a vblock it does not deal
with updates. This is because the vblock is created once at the start and
does not have a method to update itself later, after all the entry
contents are finalised.
Fix this by adjusting how the vblock is created.
Also simplify Image.ProcessEntryContents() since it effectively duplicates
the code in Section.ProcessContents().
Signed-off-by: Simon Glass <sjg@chromium.org>
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.

Refactor the implementation slightly so that section data is not
rebuilt when it is already available.
We still have GetData() set up to rebuild the section, since we don't
currently track when things change that might affect a section. For
example, if a blob is updated within a section, we must rebuild it.
Tracking that would be possible but is more complex, so it left for
another time.

With the previous changes, it is now possible to compress entire

including updating the metadata.
Also update the documentation.
Signed-off-by: Simon Glass <sjg@chromium.org>
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.

At present this function assumes that the size of a section is at least as

Signed-off-by: Simon Glass <sjg@chromium.org>
This method introduces a separation between packing and checking that is
different for sections. In order to handle compression properly, we need
to be able to deal with a section's size being smaller than the
uncompressed size of its contents. It is easier to make this work if
everything happens in the Pack() method.
