Add a new entry argument to the fit entry which allows selection of the default configuration to use. This is the 'default' property in the 'configurations' node.
Update the Makefile to pass in the value of DEVICE_TREE or CONFIG_DEFAULT_DEVICE_TREE to provide this information.
Signed-off-by: Simon Glass sjg@chromium.org Suggested-by: Michal Simek michal.simek@xilinx.com ---
Changes in v4: - Add more documentation for DEFAULT-SEQ
Changes in v3: - Rebase on top of earlier binman series
Changes in v2: - Add new patch to allow selecting default FIT configuration
