Commit Message

  Sometimes the contents of a partition are compressed. Add a property to
express this and define the algorithm used.

Signed-off-by: Simon Glass <sjg@chromium.org>

Changes in v4:
- Add an example

Changes in v3:
- Just add a compression property for now

Changes in v2:
- Use "binman" for compatible instead of "u-boot,binman"
- Significantly rework the patch
- Use make dt_binding_check DT_SCHEMA_FILES=Documentation/../partitions
