As per the centithread on ksummit-discuss [1], there are folks who
feel that if a Change-Id is present in a developer's local commit that
said Change-Id could be interesting to include in upstream posts.
Specifically if two commits are posted with the same Change-Id there's
a reasonable chance that they are either the same commit or a newer
version of the same commit. Specifically this is because that's how
gerrit has trained people to work.
There is much angst about Change-Id in upstream Linux, but one thing
that seems safe and non-controversial is to include the Change-Id as
part of the string of crud that makes up a Message-Id.
Let's give that a try.
In theory (if there is enough adoption) this could help a tool more
reliably find various versions of a commit. This actually might work
pretty well for U-Boot where (I believe) quite a number of developers
use patman, so there could be critical mass (assuming that enough of
these people also use a git hook that adds Change-Id to their
commits). I was able to find this git hook by searching for "gerrit
change id git hook" in my favorite search engine.
In theory one could imagine something like this could be integrated
into other tools, possibly even git-send-email. Getting it into
patman seems like a sane first step, though.
NOTE: this patch is being posted using a patman containing this patch,
so you should be able to see the Message-Id of this patch and see that
it contains my local Change-Id, which ends in 2b9 if you want to
check.

At present the symbol information is written to binaries just before
binman exits. This is fine for entries within sections since the section
contents is calculated when it is needed, so the updated symbol values are
included in the image that is written.
However some binaries are inside entries which have already generated
their contents and do not notice that the entries have changed (e.g. Intel
IFWI).
Move the symbol writing earlier to cope with this.

At present these are large enough to hold 20 bytes of symbol data. Add

Unfortunately at present this involves changing a few test files to make

Entries which include a section and need to obtain its contents call
GetData(), as with any other entry. But the current implementation of this
method in entry_Section requires the size of the section to be known. If
it is unknown, an error is produced, since size is None:
TypeError: can't multiply sequence by non-int of type 'NoneType'

adjusted to build up the section piece by piece, instead of patching each
entry into an existing bytearray.

At present binman has a single entry type for the 16-bit code code needed

reset vector itself as well as the code to move to 32-bit mode.
However this is not very flexible since in some cases other data needs to
be included at the top of the SPI flash, in between these two pieces. For
example Intel requires that a FIT (Firmware Image Table) pointer be placed
0x40 bytes before the end of the ROM.

subsequent change will adjust the existing 'start16' entry.

be determined without reference to the size of the containing entry. This
allows the entry to be larger that the contents, without causing errors in
decompression. This is necessary to cope with a compressed device tree
being updated in such a way that it shrinks after the entry size is
already set (an obscure case). It is not used with CBFS since it has its
own metadata for this. Increase the number of passes allowed to resolve
the position of entries, to handle this case.

ReadData() method to provide the data by calling a new ReadChildData()
method in the parent. This allows the entry_Section class, or possibly
any other container class, to return the correct data in all cases.

The Intel descriptor must always appear at the start of an (x86) image,
so it is supposed to position itself there always. However there is no
explicit test for this. Add one and fix a bug introduced by the recent
change to adjust Entry to read the node in a separate call.

The FMAP is not intended to show the files inside a CBFS. The FMAP can be
used to locate the CBFS itself, but then the CBFS must be read to find out
what is in it.
Update the FMAP to work this way and add some debugging while we are here.

Sometimes an entry may shrink after it has already been packed. In that
case we must repack the items. Of course it is always possible to just
leave the entry at its original size and waste space at the end. This is
what binman does by default, since there is the possibility of the entry
changing size every time binman calculates its contents, thus causing a
loop.

Sometimes entries shrink after packing. As a start towards supporting
this, update the _testing entry to handle the test case.

So far we don't allow entries to change size when repacking. But this is
not very useful since it is common for entries to change size after an
updated binary is built, etc.
Add support for this, respecting the original offset/size/alignment
constraints of the image layout. For this to work the original image
must have been created with the 'allow-repack' property.
This does not support entry types with sub-entries such as files and
CBFS, but it does support sections.

The positioning does not currently work correctly if at the end of an
image with no fixed size. Also if the header is in the middle of an image
it can cause a gap in the image since the header position is normally at
the image end, so entries after it are placed after the end of the image.
Fix these problems and add more tests to cover these cases.

Now that an Image is an Entry_section, there is no need for the separate
BuildSection() function. Drop it and add a bit of logging.

When reading an image in, write its fdtmap to a file in the output
directory. This is useful for debugging. Update the 'ls' command to set up
the output directory; otherwise it will fail.

At present it is not possible to discover the contraints to repacking an
image (e.g. maximum section size) since this information is not preserved
from the original image description.
Add new 'orig-offset' and 'orig-size' properties to hold this. Add them to
the main device tree in the image.

While it is useful and efficient to build images in a single pass from a
unified description, it is sometimes desirable to update the image later.
Add support for replace an existing file with one of the same size. This
avoids needing to repack the file. Support for more advanced updates will
come in future patches.
