[U-Boot] [PATCH v2 4/8] test: py: add option to select device tree used during compilation

[Patrick Delaunay]

Only used for spl compilation which include the device tree
(with platdata or embedded device tree).
For U-boot, test use config.dtb, by default :
   "build_dir + '/arch/sandbox/dts/test.dtb'"

I need to force o_dt = 'all' to avoid make error:

make: *** empty string invalid as file name.  Stop.

But, I don't sure that it is the better solution for pytest.


Changes in v2:
- add a new test option: device tree used for compilation
