* There are two types of tests in this file:
|
|
|
|
* - normal ones which act on the control FDT (gd->fdt_blob or gd->of_root)
|
|
|
|
* - 'other' ones which act on the 'other' FDT (other.dts)
|
|
|
|
*
|
|
|
|
* The 'other' ones have an _ot suffix.
|
|
|
|
*
|
|
|
|
* The latter are used to check behaviour with multiple device trees,
|
|
|
|
* particularly with flat tree, where a tree ID is included in ofnode as part of
|
|
|
|
* the node offset. These tests are typically just for making sure that the
|
|
|
|
* offset makes it to libfdt correctly and that the resulting return value is
|
|
|
|
* correctly turned into an ofnode. The 'other' tests do not fully check the
|
|
|
|
* behaviour of each ofnode function, since that is done by the normal ones.
