When support for sections (and thus hierarchical images) was added to
binman, the decision was made to create a new Section class which could
be used by both Image and an Entry_section class. The decision between
using inheritance and composition was tricky to make, but in the end it
was decided that Image was different enough from Entry that it made sense
to put the implementation of sections in an entirely separate class. It
also has the advantage that core Image code does have to rely on an entry
class in the etype directory.
This work was mostly completed in commit:
8f1da50ccc "binman: Refactor much of the image code into 'section'
As a result of this, the Section class has its own version of things like
offset and size and these must be kept in sync with the parent
Entry_section class in some cases.
In the last year it has become apparent that the cost of keeping things in
sync is larger than expected, since more and more code wants to access
these properties.
An alternative approach, previously considered and rejected, now seems
better.
Adjust Image to be a subclass of Entry_section. Move the code from Section
(in bsection.py) to Entry_section and delete Section. Update all tests
accordingly.
This requires substantial changes to Image. Overall the changes reduce
code size by about 240 lines. While much of that is just boilerplate from
Section, there are quite a few functions in Entry_section which now do not
need to be overiden from Entry. This suggests the change is beneficial
even without further functionality being added.
A side benefit is that the properties of sections are now consistent with
other entries. This fixes a problem in testListCmd() where some properties
are missing for sections.
Unfortunately this is a very large commit since it is not feasible to do
the migration piecemeal. Given the substantial tests available and the
100% code coverage of binman, we should be able to do this safely.

The purpose of this badly named field is a bit ambiguous. Adjust the code
to use it only to store the uncompressed length of a file, leaving it set
to None if there is no compression used. This makes it easy to see if the
value in this field is relevant / useful.
Also set data_len for compressed fields, since it should be the length of
the compressed data, not the uncompressed data.

Add support for detecting entries that change size after they have already

Signed-off-by: Simon Glass <sjg@chromium.org>
We plan to support changing the size of entries after they have been
packed. For now it will always be enabled. But to aid testing of both
cases (in the event that we want to add a command-line flag, for example),
add a setting to control it.
Signed-off-by: Simon Glass <sjg@chromium.org>
At present if this function tries to update the contents such that the
size changes, it raises an error. We plan to add the ability to change
the size of entries after packing is completed, since in some cases it is
not possible to determine the size in advance.
An example of this is with a compressed device tree, where the values
of the device tree change in SetCalculatedProperties() or
ProcessEntryContents(). While the device tree itself does not change size,
since placeholders for any new properties have already bee added by
AddMissingProperties(), we cannot predict the size of the device tree
after compression. If a value changes from 0 to 0x1234 (say), then the
compressed device tree may expand.
As a first step towards supporting this, make ProcessContentsUpdate()
return a value indicating whether the content size is OK. For now this is
always True (since otherwise binman raises an error), but later patches
will adjust this.
Signed-off-by: Simon Glass <sjg@chromium.org>
SetContents() should only be called to set the contents of an entry from
within the ObtainContents() call, since it has no guard against increasing
the size of the contents, thus triggering incorrect operation.
Change all such calls to use ProcessUpdateContents() instead.

At present entry modules can only be accessed using Entry.Lookup() or

Compression is currently available only with blobs. However we want to
report the compression algorithm and uncompressed size for all entries,
so that other entry types can support compression. This will help with

It is useful to be able to quickly locate the FDT map in the image. An
easy way to do this is with a pointer at the start or end of the image.
Add an 'image header' entry, which places a magic number followed by a
pointer to the FDT map. This can be located at the start or end of the
image, or at a chosen location.
As part of this, update GetSiblingImagePos() to detect missing siblings.

An FDT map is an entry which holds a full description of the image

Signed-off-by: Simon Glass <sjg@chromium.org>
The current test for the 'entry' module is a bit convoluted since it has
to import the module multiple times. It also relies on ordering, in that
test1EntryNoImportLib() must run before test2EntryImportLib() if they are
running in the same Python process.
This is unreliable since neither the ordering of tests nor the process
that they run in is defined.
Fix this by always reloading the entry in these two tests. Also add a
check that the expected value of have_importlib is obtained.
This corrects a code-coverage problem in the 'entry' module on some
systems.

Coreboot uses a simple flash-based filesystem called Coreboot Filesystem
(CBFS) to organise files used during boot. This allows files to be named
and their position in the flash to be set. It has special features for
dealing with x86 devices which typically memory-map their SPI flash to the
top of 32-bit address space and need a 'boot block' ending there.

writer class, a reader class and associated other helpers. Only a subset
of features are currently supported.

Add support for A/B boot process on AM57xx based boards:
1. Define 'slot_suffix' variable (using 'ab_select' command)
2. Extend 'emmc_android_boot' boot command (add commands for A/B boot
process)
'ab_select' command is used to decide which slot should be used for
booting up. A/B metadata resides in 'misc' partition.
To activate the A/B boot process, the following config options must be
set:
CONFIG_ANDROID_AB=y
CONFIG_CMD_AB_SELECT=y
For successful A/B boot, the corresponding A/B infrastructure must be
involved on Android side [1] (including mounting system as root), and
disk must be partitioned accordingly.
When A/B boot is enabled, there are some known limitations currently
exist (not related to A/B patches, need to be implemented later):
1. The 'Verified Boot' sequence is not supported
2. dev path to system partition (system_a or system_b) is passed via
'bootargs' as 'root=' argument like 'root=/dev/mmcblk1p12', but
further we'll need to rework it with respect to dm-verity
requirements [2]
In case when A/B partitions are not present in system (and A/B boot is
enabled), boot up process will be terminated and next message will be
shown:
"boot_a(b) partition not found"
