of: Eliminate of_allnodes list

2014-11-04T13:29:38+00:00

The device tree structure is composed of two lists; the 'allnodes' list
which is a singly linked list containing every node in the tree, and the
child->parent structure where each parent node has a singly linked list
of children. All of the data in the allnodes list can be easily
reproduced with the parent-child lists, so of_allnodes is actually
unnecessary. Remove it entirely which saves a bit of memory and
simplifies the data structure quite a lot.

of/promtree: add package-to-path support to pdt

2010-10-13T03:58:08+00:00

package-to-path is a PROM function which tells us the real (full) name of the
node.  This provides a hook for that in the prom ops struct, and makes use
of it in the pdt code when attempting to determine a node's name.  If the
hook is available, try using it (falling back to looking at the "name"
property if it fails).

of/promtree: add of_pdt namespace to pdt code

2010-10-13T03:58:00+00:00

For symbols still lacking namespace qualifiers, add an of_pdt_ prefix.

of/promtree: no longer call prom_ functions directly; use an ops structure

2010-10-13T03:57:53+00:00

Rather than assuming an architecture defines prom_getchild and friends,
define an ops struct with hooks for the various prom functions that
pdt.c needs.  This ops struct is filled in by the
arch-(and sometimes firmware-)specific code, and passed to
of_pdt_build_devicetree.

Update sparc code to define the ops struct as well.

of/promtree: make drivers/of/pdt.c no longer sparc-only

2010-10-11T03:53:30+00:00

Clean up pdt.c:
 - make build dependent upon config OF_PROMTREE
 - #ifdef out the sparc-specific stuff
 - create pdt-specific header
