Allow device tree to be modified by additonal device tree sections This patch allows the following construct: / { property-a = "old"; property-b = "does not change"; }; / { property-a = "changed"; property-c = "new"; node-a { }; }; Where the later device tree overrides the properties found in the earlier tree. This is useful for laying down a template device tree in an include file and modifying it for a specific board without having to clone the entire tree.

Ensure all tests have matching reg and unit address ePAPR 1.1 section 2.2.1.1 "Node Name Requirements" specifies that any node that has a reg property must include a unit address in its name with value matching the first entry in its reg property. Conversely, if a node does not have a reg property, the node name must not include a unit address. Adjust all the dtc test-cases to conform to this rule.

libfdt: Add helpers for 64-bit integer properties In device trees in the world, properties consisting of a single 64-bit integer are not as common as those consisting of a single 32-bit, cell sized integer, but they're common enough that they're worth including convenience functions for. This patch adds helper wrappers of fdt_setprop_inplace(), fdt_setprop() and fdt_appendprop() for handling 64-bit integer quantities in properties. For better consistency with the names of these new *_u64() functions we also add *_u32() functions as alternative names for the existing *_cell() functions handling 32-bit integers.

Add merging of labelled subnodes. This patch allows the following syntax: / { child { label: subchild { }; }; }; &label { prop = "value"; }; which will result in the following tree: / { child { label: subchild { prop = "value"; }; }; }; Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
