At present on large files, lz4 uses a larger block size (e.g. 256KB) than
the 64KB supported by the U-Boot decompression implementation. Also it is
optimised for maximum compression speed, producing larger output than we
would like.
Update the parameters to correct these problems.

At present binman only supports resolving symbols in the same section as
the binary that uses it. This is quite limited because we often need to
group entries into different sections.
Enhance the algorithm to search the entire image for symbols.

Normally when an entry is created, any entry arguments it has are required
to be provided, so it can actually generate its contents correctly.
However when an existing image is read, Entry objects are created for each
of the entries in the image. This happens as part of the process of
reading the image into binman.
In this case we don't need the entry arguments, since we do not intend to
regenerate the entries, or at least not unless requested. So there is no
sense in reporting an error for missing entry arguments.
Add a new property for the Image to handle this case. Update the error
reporting to be conditional on this property.

To: u-boot
At present if a devicetree blob is included in a vblock it does not deal
with updates. This is because the vblock is created once at the start and
does not have a method to update itself later, after all the entry
contents are finalised.
Fix this by adjusting how the vblock is created.
Also simplify Image.ProcessEntryContents() since it effectively duplicates
the code in Section.ProcessContents().

The offset of an entry needs to be adjusted by its skip-at-start value.
This is currently missing when reading entry data. Fix it.

At present if a devicetree blob is included in a vblock it does not deal
with updates. This is because the vblock is created once at the start and
does not have a method to update itself later, after all the entry
contents are finalised.
Fix this by adjusting how the vblock is created.
Also simplify Image.ProcessEntryContents() since it effectively duplicates
the code in Section.ProcessContents().

Normally when an entry is created, any entry arguments it has are required
to be provided, so it can actually generate its contents correctly.
However when an existing image is read, Entry objects are created for each
of the entries in the image. This happens as part of the process of
reading the image into binman.
In this case we don't need the entry arguments, since we do not intend to
regenerate the entries, or at least not unless requested. So there is no
sense in reporting an error for missing entry arguments.
Add a new property for the Image to handle this case. Update the error
reporting to be conditional on this property.

At present binman only supports resolving symbols in the same section as
the binary that uses it. This is quite limited because we often need to
group entries into different sections.
Enhance the algorithm to search the entire image for symbols.

At present on large files, lz4 uses a larger block size (e.g. 256KB) than
the 64KB supported by the U-Boot decompression implementation. Also it is
optimised for maximum compression speed, producing larger output than we
would like.
Update the parameters to correct these problems.
