Add an optional length header attribute to the device tree blob entry
class based on the compressed data header from the utilities to compress
and decompress data.
If needed the header could be enabled with the following
attribute beside the compress attribute:
prepend = "length";
The header was introduced as part of commit eb0f4a4cb4 ("binman:
Support replacing data in a cbfs") to allow device tree entries to be
larger than the compressed contents. Regarding the commit "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)". This case need to be fixed without influence any compressed data
by itself.

At present the collections etype only works with entries in the same
section. This can be limiting, since in some cases the data may be inside
a subsection, e.g. if there are alignment constraints.
Add a function to find the entries in an etype and have it search
recursively. Make use of this for mkimage also.

Some boards need to load an ELF file using the 'loadables' property, but
the file has segments at different memory addresses. This means that it
cannot be supplied as a flat binary.
Allow generating a separate node in the FIT for each segment in the ELF,
with a different load address for each.
Also add checks that the fit,xxx directives are valid.

At present the 'args' property of the mkimage entry type is a string. This
makes it difficult to include CONFIG options in that property. In
particular, this does not work:
args = "-n CONFIG_SYS_SOC -E"
since the preprocessor does not operate within strings, nor does this:
args = "-n" CONFIG_SYS_SOC" "-E"
since the device tree compiler does not understand string concatenation.
With this new feature, we can do:
args = "-n", CONFIG_SYS_SOC, "-E";

Sometimes it is useful to have a list of related external blobs in a
single entry. An example is the DDR binaries used by meson. There are

In some cases entries encapsulate other data and it is useful to access
the data within. An example is the fdtmap which consists of a 16-byte
header, followed by a devicetree.
Provide an option to specify an alternative format when extracting files.
In the case of fdtmap, this is 'fdt', which produces an FDT file which can
be viewed with fdtdump.

The vblock entry type includes code to collect the data from a number of
