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
four more bytes so we can add another test.
Unfortunately at present this involves changing a few test files to make
room. We could adjust the test files to not specify sizes for entries.
Then we could make the tests check the actual sizes. But for now, leave it
as it is, since the effort is minor.
Signed-off-by: Simon Glass <sjg@chromium.org>
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'
There is no need to know the size in advance since the code can be
adjusted to build up the section piece by piece, instead of patching each
entry into an existing bytearray.

Signed-off-by: Simon Glass <sjg@chromium.org>
At present binman has a single entry type for the 16-bit code code needed
to start up an x86 processor. This entry is intended to include both the
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.
To deal with this, add a new reset entry for just the reset vector. A
subsequent change will adjust the existing 'start16' entry.

At present binman cannot replace data within a CBFS since it does not

Add a header to compressed data so that the amount of compressed data can
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.

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.

At present EnsureCompiled() uses an file from the 'output' directory (in
the tools module) when compiling the device tree. This is fine in most
cases, allowing useful inspection of the output files from binman.
However in functional tests, _SetupDtb() creates an output directory and
immediately removes it afterwards. This serves no benefit and just
confuses things, since the 'official' output directory is supposed to be
created and destroyed in control.Binman().
Add a new parameter for the optional temporary directory to use, and use a
separate temporary directory in _SetupDtb().

When updating an existing image where the size of all entries remains the
same, we should not need to regenerate the fdtmap. Update the entry to
return the same fdtmap as was read from the image.

We use this same combination of properties several times in tests. Add a
constant for it to avoid typos, etc.

At present we have an 'image' property in the entry for this purpose, but
this is not necessary and seems error-prone in the presence of
inheritance. Add a function instead. The Entry_section class overrides
this with a special version, since top-level sections are in fact images,
since Image inherits Entry_section.

At present the Entry constructor sets up the object and then immediately
reads its device-tree node to obtain its properties.
This breaks a convention that constructors should not do any processing.
A consequence is that we must pass all arguments to the constructor and
cannot have the node-reading proceed in a different way unless we pass
flags to that constructor. We already have a 'test' flag in a few cases,
and now need to control whether the 'orig_offset' and 'orig_size'
properties are set or not.
Adjust the code to require a separate call to ReadNode() after
construction. The Image class remains as it was.

Since binman supports multiple images it is useful to know which one
created the image that has been read. Then it is possible to look up that
name in the 'master' device tree (containing the description of all
images).
Add a property for this.

In some cases we want to access the Entry object for a particular device
tree. This allows us to read its contents or update it. Add this
information to output_fdt_files and provide a function to read it.
Also rename output_fdt_files since its name is no-longer descriptive.
