Binman lets us declare symbols in SPL/TPL that refer to other entries in
the same binman image as them. These symbols are filled in with the
correct values while binman assembles the images, but this is done
in-memory only. Symbols marked as optional can be filled with
BINMAN_SYM_MISSING as an error value if their referred entry is missing.
However, the unmodified SPL/TPL binaries are still available on disk,
and can be used by people. For these files, nothing ensures that the
symbols are set to this error value, and they will be considered valid
when they are not.
Empirically, all symbols show up as zero in a sandbox_vpl build when we
run e.g. tpl/u-boot-tpl directly. On the other hand, zero is a perfectly
fine value for a binman-written symbol, so we cannot say the symbols
have wrong values based on that.
Declare a magic symbol that binman always fills in with a fixed value.
Check this value as an indicator that symbols were filled in correctly.
Return the error value for all symbols when this magic symbol has the
wrong value.
For binman tests, we need to make room for the new symbol in the mocked
SPL/TPL data by extending them by four bytes. This messes up some test
image layouts. Fix the affected values, and check the magic symbol
wherever it makes sense.

Binman interfaces allow attempts to replace any entry in the image with
arbitrary data. When trying to replace sections, the changes in the
section entry's data are not propagated to its child entries. This,
combined with how sections rebuild their contents from its children,
eventually causes the replaced contents to be silently overwritten by
rebuilt contents equivalent to the original data.

Binman FIT entry nodes describe their subentries in an 'images' subnode,
same as how they would be written for the mkimage executable. The entry
type initially manually managed its subentries keyed by their node paths
relative to its base node. It was later converted to a proper section
while still keeping the same keys for subentries.
These subentry keys of sections are used as path fragments, so they must
not contain the path separator character '/'. Otherwise, they won't be
addressable by binman extract/replace commands. Change these keys from
the '/images/foo' forms to the subentry node names. Extend the simple

When an image has the 'allow-repack' property, binman includes the
original offset and size properties from the image description in the
fdtmap. These are later used as the packing constraints when replacing
entries in an image, so other unconstrained entries can be freely
positioned.
Replacing an entry in an image without 'allow-repack' (and therefore the
original offsets) follows the same logic and results in entries being
merely concatenated. Instead, skip resetting the calculated offsets and
sizes to the missing originals for these images so that every entry is
constrained to its existing offset/size.
Add tests that replace an entry with smaller or equal-sized data, in an
image that doesn't allow repacking. Attempting to do so with bigger-size
data is already an error that is already being tested.

Binman can embed a copy of the image description into the images it
builds as a fdtmap entry, but it omits the /binman/<image-name> prefix
from the node paths while doing so. When reading an already-built image
file, entries are reconstructed using this fdtmap and their associated
nodes still lack that prefix.
Some entries like fit and vblock create intermediate files whose names
are based on an entry unique name. This name is constructed from their
node's path by concatenating the parents with dots up to the binman
node, e.g. /binman/image/foo/bar becomes 'image.foo.bar'.
However, we don't have this /binman/image prefix when replacing entries
in such an image. The /foo/bar entry we read when doing so erroneously
has the unique name of '/.foo.bar', causing permission errors when the
entry attempts to create files based on that.
Fix the unique-name generation by stopping at the '/' node like how it
stops at the binman node. As the unique names are used as filenames, add
tests that check if they're safe to use as filenames.

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

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

Generally the content of sections is not built until the final assembly

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

Add a new command-line option to disable expanded entries. This is needed
for most tests, since it is much easier to 'factor out' this function into
a separate test and keep the existing packing tests simple.
Add the option and select it by default from tests.

The offset of an entry needs to be adjusted by its skip-at-start value.

When packing files it is sometimes useful to align the start of each file,
e.g. if the flash driver can only access 32-bit-aligned data. Provides a
new property to support this.

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().

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.

At present binman only supports resolving symbols in the same section as
the binary that uses it. This is quite limited because we often need to
group entries into different sections.
Enhance the algorithm to search the entire image for symbols.

With the previous changes, it is now possible to compress entire
sections. Add some tests to check that compression works correctly,
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.

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.

When compressing an entry, the original uncompressed data is overwritten.

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.

Each section is padded up to its size, if the contents are not large
enough. Move this logic from _BuildSectionData() to
GetPaddedDataForEntry() so that all the padding is in one place.
With this, the testDual test is working again, so enable it.

Create a new _BuildSectionData() to hold the code that is now in
GetData(), so that it is clearly separated from entry.GetData() base
function.
Separate out the 'pad-before' processing to make this easier to
understand.
Unfortunately this breaks the testDual test. Rather than squash several
patches into an un-reviewable glob, disable the test for now.
This also affects testSkipAtStartSectionPad(), although it still not
quite what it should be. Update that temporarily for now.
