Although it's a low-level function that shouldn't normally be needed, there are circumstances where it's useful for users of libfdt to use the _fdt_next_tag() function. Therefore, this patch renames it to fdt_next_tag() and publishes it in libfdt.h. In addition, this patch adds a new testcase using fdt_next_tag(), dtbs_equal_ordered. This testcase tests for structural equality of two dtbs, including the order of properties and subnodes, but ignoring NOP tags, the order of the dtb sections and the layout of strings in the strings block. This will be useful for testing other dtc functionality in the future. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
