b290428d71 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.

cbf1410eab 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.

8773e12fa9 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";
		};
	};
};
