[PATCH v2 0/7] support overlays to the barebox live tree

[Sascha Hauer <s.hauer@pengutronix.de>]

Support for applying a device tree overlay to the barebox live tree
is already present. This series adds a few missing pieces:

- add support for applying overlays to the live tree from the command
  line
- add support for adding new I2C/SPI devices via overlays
- add Makefile magic to build dtbo files and dtbo.o files to include
  into the barebox binary from dtso files

Changes since v1:
- add a device_rescan() static inline wrapper
- add missing call to of_i2c_register_devices() in i2c_add_numbered_adapter()
- replace device_detect with device_rescan in of_device_create_on_demand()

Sascha Hauer (7):
  kbuild: Add target to build dtb overlay files
  driver: Add rescan hook to struct device
  i2c: implement rescan
  spi: Directly register SPI device
  spi: reduce scope of 'chip'
  spi: implement rescan
  of_overlay: Add option to apply overlay to live tree
