[Pdbg] [PATCH v3 0/4] Fix handling of attributes for virtual targets

The system level attributes are assigned to the root (/) of the tree. So
make sure that the pdbg_root is associated with root of the system tree.
Since system tree includes few virtual targets (e.g. /proc0/pib), any
attributes defined for such targets need to be found for the corresponding
real targets.

V2 changes:
 - Fix a bug in checking if fdt is writeable
 - Improve the check if fdt is writeable, takes care of readonly mmaps

V3 changes:
 - Change pdbg_fdt_is_writeable() to pdbg_fdt_is_readonly()
   This avoids unnecessary logic negation

Amitay Isaacs (4):
  libpdbg: Properties for / in system tree are attached to root node
  libpdbg: Handle properties defined on virtual targets correctly
  tests: Assign attributes to virtual nodes to test property api
  libpdbg: Improve the logic to check if fdt is writable
