libfdt: Add version.lds file Add the initial symbol versioning file as groundwork for creating a libfdt shared library Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com>

libfdt: Add fdt_path_offset_namelen() Properties may contain path names which are not NUL-terminated. For example, the 'stdout-path' property allows the form 'path:options', where the ':' character terminates the path specifier. Allow these path names to be used in-place for path descending; add fdt_path_offset_namelen(), which limits the path name to 'namelen' characters. Reimplement fdt_path_offset() as a trivial wrapper.

libfdt: De-inline fdt_header_size() There does not seem to be a strong reason to inline this function. Also we are about to add some extra code to it which will increase its size.

libfdt: Safer access to strings section fdt_string() is used to retrieve strings from a DT blob's strings section. It's rarely used directly, but is widely used internally. However, it doesn't do any bounds checking, which means in the case of a corrupted blob it could access bad memory, which libfdt is supposed to avoid. This write a safe alternative to fdt_string, fdt_get_string(). It checks both that the given offset is within the string section and that the string it points to is properly \0 terminated within the section. It also returns the string's length as a convenience (since it needs to determine to do the checks anyway). fdt_string() is rewritten in terms of fdt_get_string() for compatibility. Most of the diff here is actually testing infrastructure.

libfdt: Add new maximum phandle lookup function The fdt_get_max_phandle() function has some shortcomings. On one hand it returns just a uint32_t which means to check for the "negative" error code a caller has to explicitly check against the error code (uint32_t)-1. In addition, the -1 is the only error code that can be returned, so a caller cannot tell the difference between the various failures. Fix this by adding a new fdt_find_max_phandle() function that returns an error code on failure and 0 on success, just like other APIs, and stores the maximum phandle value in an output argument on success. This also refactors fdt_get_max_phandle() to use the new function. Add a note pointing out that the new fdt_find_max_phandle() function should be preferred over fdt_get_max_phandle().

libfdt: Add phandle generation helper The new fdt_generate_phandle() function can be used to generate a new, unused phandle given a specific device tree blob. The implementation is somewhat naive in that it simply walks the entire device tree to find the highest phandle value and then returns a phandle value one higher than that. A more clever implementation might try to find holes in the current set of phandle values and fill them. But this implementation is relatively simple and works reliably. Also add a test that validates that phandles generated by this new API are indeed unique.

Link tools and tests against libfdt shared library Currently the libfdt based tools (fdtput, fdtget, etc.) and all the test binaries using libfdt are linked against the static version of libfdt. That's made it very easy in the past to forget to properly update the version.lds file which is needed to make functions publicaly accessible from the shared library. To avoid problems like that in future, alter the build so that we link and run the tests against the shared library version of libfdt. That immediately points out several important symbols that are still missing from the version.lds, so fix those as well. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

libfdt: Introduce fdt_create_with_flags() There is a need to be able to specify some options when building an FDT with the SW interface. This can be accomplished with minimal changes by storing intermediate data in the fdt header itself, in fields that are not otherwise needed during the creation process and can be set by fdt_finish(). The fdt.magic field is already used exactly this way, as a state to check with callers that the FDT has been created but not yet finished. fdt.version and fdt.last_comp_version are used to make room for more intermediate state. These are adjacent and unused during the building process. last_comp_version is not yet used for intermediate state, but it is zeroed and treated as used, so as to allow future growth easily. A new interface, fdt_create_with_flags() is added, which takes 32-bit flag value to control creation.
