[PATCH v3 0/2] of: Add unit tests for applying overlays

Show all headers | View raw

From: Frank Rowand <frank.rowand@sony.com>

Existing overlay unit tests examine individual pieces of the overlay
code.  The new tests target the entire process of applying an overlay.

Changes from v2:
  - of_private.h: move __unflatten_device_tree() outside
    #ifdef CONFIG_OF_UNITTEST
  - unittest.c: move overlay declaration macros outside #ifdef CONFIG_OF_OVERLAY
  - unittest.c: make overlay_info overlays[] static
  - unittest.c: remove extra blank line

Changes from v1:
  - Move overlay base dtb unflattening into unittest.c.  Call from fdt.c.
  - Clarify file and variable names, 'overlay_test_' instead of 'ot_'
  - Use proper naming convention for node names.
  - A few added comments.
  - Improve error messages in the new tests.

  of: support dtc compiler flags for overlays
