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

From: frowand . list
Date: Tue Apr 25 2017 - 14:36:18 EST


From: Frank Rowand <frank.rowand@xxxxxxxx>

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.

Frank Rowand (2):
of: support dtc compiler flags for overlays
