82337bb6b6 binman: Refuse to replace sections for now
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.

Add a simple test for replacing a section that is currently failing due
to this behaviour, and mark it as an expected failure. Also, raise an
error when replacing a section instead of silently pretending it was
replaced.

99283e5389 binman: Test replacing non-section entries in FIT subsections
A previous patch fixes binman to correctly extract FIT subentries. This
makes it easier to test replacing these entries as we can write tests
using an existing helper function that relies on extracting the replaced
entry.

Add tests that replace leaf entries in FIT subsections with data of
various sizes. Replacing the subsections or the whole FIT section does
not work yet due to the section contents being re-built from unreplaced
subentries' data.

74d3b2311d binman: Create FIT subentries in the FIT section, not its parent
When reading images from a file, each entry's data is read from its
parent section as specified in the Entry.Create() call that created it.
The FIT entry type has been creating its subentries under its parent
(their grandparent), as creating them under the FIT entry resulted in an
error until FIT was converted into a proper section.

FIT subentries have their offsets relative to the FIT section, and
reading those offsets in the parent section results in wrong data. The
subentries rightfully belong under the FIT entries, so create them
there. Add tests checking that we can extract the correct data for a FIT
entry and its subentries.

e736878b08 binman: Remove '/images/' fragment from FIT subentry paths
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
FIT tests to check for this.

e2ce4fb986 binman: Don't reset offset/size if image doesn't allow repacking
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.

8ee4ec9bf5 binman: Collect bintools for images when replacing entries
Binman entries can use other executables to compute their data, usually
in their ObtainContents() methods. Subclasses of Entry_section would use
bintools in their BuildSectionData() method instead, which is called
from several places including their Pack().

These binary tools are resolved correctly while building an image from a
device-tree description so that they can be used from these methods.
However, this is not being done when replacing entries in an image,
which can result in an error as the Pack() methods attempt to use them.

Collect and resolve entries' bintools also when replacing entries to fix
Pack() errors. Add a way to mock bintool usage in the testing entry type
and tests that check bintools are being resolved for such an entry.

67bf2c8ded binman: Fix unique names having '/.' for images read from files
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.

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.

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.

Section does not use any binary tools itself. However, this means the
check is also skipped for subclasses of Section which might need binary
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.

ed293c3221 binman: Register and check bintools from FIT subentries
Binman keeps track of binary tools each entry wants to use. The
implementation of this for the FIT entry only adds "mkimage", but not
the tools that would be used by its subentries.

Register the binary tools that FIT subentries will use in addition to
the one FIT itself uses, and check their existence by copying the
appropriate method from Section entry type. Also add tests that check if
these subentries can use and warn about binary tools.

21353311ff binman: Fix subentry expansion for FIT entry type
Binman tries to expand some entries into parts that make it up, e.g.
'u-boot' into a 'u-boot-expanded' section that contains 'u-boot-nodtb'
and 'u-boot-dtb'. Entries with child entries must call ExpandEntries()
on them to build a correct image, as it's possible that unexpanded child
entries have no data of their own. The FIT entry type doesn't currently
do this, which means putting a "u-boot" entry inside it doesn't work as
expected.

Implement ExpandEntries() for FIT and add a copy of a simple FIT image
test that checks subentry expansion in FIT entries.

252ac58996 patman: Rename Color() method to build()
This method has the same name as its class which is confusing. It is also
annoying when searching the code.

It builds a string with a colour, so rename it to build().
