Add a link to binman's documentation and adjust the files so that it is
accessible. Use the name README.rst so it is easy to discover when binman
is installed without U-Boot.

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 {
type = "section";
u-boot-nodtb {
};
u-boot-dtb {
};
};
Add an implementaion of this and associated documentation.

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.

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.
The only real user of CheckEntries() is entry_Section and it can call it
directly. Drop the call from 'control' and handle it locally.

This is only used by entry_Section and that class already calls it. Avoid

When binman is in use, most of the targets built by the Makefile are
inputs to binman. We then need a final rule to run binman to produce the
final outputs.
Rename the variable to indicate this, and add a new 'inputs' target.

A recent change adjusted the symbol calculation to work on x86 but broke
it for Tegra. In fact this is because they have different needs.
On x86 devices the code is linked to a ROM address and the end-at-4gb
property is used for the image. In this case there is no need to add the
base address of the image, since the base address is already built into
the offset and image-pos properties.
On other devices we must add the base address since the offsets start at
zero.
In addition the base address is currently added to the 'offset' and 'size'
values. It should in fact only be added to 'image-pos', since 'offset' is
relative to its parent and 'size' is not actually an address. This code
should have been adjusted when support for 'image-pos' and 'size' was
added, but it was not.
To correct these problems:
- move the code that handles adding the base address to section.py, which
can check the end-at-4gb property and which property
(offset/size/image-pos) is being read
- add the base address only when needed (only for image-pos and not if the
image uses end-at-4gb)
- add a note to the documentation
- add a separate test to cover x86 behaviour

The doc currently uses sandbox_defconfig as examples of enabling

does not call binman at all. Change it to qemu-x86_defconfig.

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.

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.

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
the forthcoming 'list' feature which lists entries in the image.

which had the wrong property name.

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
entries, in FDT format. It can be discovered using the magic string at
its start. Tools can locate and read this entry to find out what entries
are in the image and where each entry is located.

Currently binman calculates '_skip_at_start' based on 'end-at-4gb'
property and it is used for x86 images.
For PowerPC mpc85xx based CPU, CONFIG_SYS_TEXT_BASE is the entry
offset of the first entry. It can be 0xeff40000 or 0xfff40000 for
nor flash boot, 0x201000 for sd boot etc, so "_skip_at_start"
should be set to CONFIG_SYS_TEXT_BASE.
'end-at-4gb' property is not applicable where CONFIG_SYS_TEXT_BASE +
Image size != 4gb.
Add new property 'skip-at-start' in Section class so that
'_skip_at_start' can be calculated either based on 'end-at-4gb'
or based on "skip-at-start".
Add a test case to check that 'skip-at-start' and 'end-at-4gb'
property can't be used together.
