libfdt: Add functions to get/add/delete memory reservemap entries This patch adds functions to libfdt for accessing the memory reservation map section of a device tree blob. fdt_num_mem_rsv() retreives the number of reservation entries in a dtb, and fdt_get_mem_rsv() retreives a specific reservation entry. fdt_add_mem_rsv() adds a new entry, and fdt_del_mem_rsv() removes a specific numbered entry. Testcases for these new functions are also included. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

tests: Avoid 64-bit arithmetic in assembler For testing we (ab)use the assembler to build us a sample dtb, independent of the other tools (dtc and libfdt) that we're trying to test. In a few places this uses 64-bit arithmetic to decompose 64-bit constants into the individual bytes in the blob. Unfortunately, it seems that some builds of GNU as don't support >32 bit arithmetic, though it's not entirely clear to me which do and which don't (Fedora i386 does support 64-bit, Debian arm32 doesn't). Anyway, to be safe, this avoids 64-bit arithmetic in assembler at the cost of some extra awkwardness because we have to define the values in 32-bit halves.

libfdt: Abolish _typed() variants, add _cell() variants In a number of places through libfdt and its tests, we have *_typed() macro variants on functions which use gcc's typeof and statement expression extensions to allow passing literals where the underlying function takes a buffer and size. These seemed like a good idea at the time, but in fact they have some problems. They use typeof and statement expressions, extensions I'd prefer to avoid for portability. Plus, they have potential gotchas - although they'll deal with the size of the thing passed, they won't deal with other representation issues (like endianness) and results could be very strange if the type of the expression passed isn't what you think it is. In fact, the only users of these _typed() macros were when the value passed is a single cell (32-bit integer). Therefore, this patch removes all these _typed() macros and replaces them with explicit _cell() variants which handle a single 32-bit integer, and which also perform endian convesions as appropriate. With this in place, it now becomes easy to use standardized big-endian representation for integer valued properties in the testcases, regardless of the platform we're running on. We therefore do that, which has the additional advantage that all the example trees created during a test run are now byte-for-byte identical regardless of platform.

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.

Remove leading underscores from identifiers In a number of places, dtc and associated tools and test code use leading _ characters on identifiers to flag them as "internal", an idiom taken from the Linux kernel. This is a bad idea in a userspace program, because identifiers with a leading _ are reserved for the C library / system. In some cases, the extra _ served no real purpose, so simply drop it. In others move to the end of the identifier, which is a convention we're free to use for our own purposes. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

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: Safer access to memory reservations fdt_num_mem_rsv() and fdt_get_mem_rsv() currently don't sanity check their parameters, or the memory reserve section offset in the header. That means that on a corrupted blob they could access outside of the range of memory that they should. This improves their safety checking, meaning they shouldn't access outside the blob's bounds, even if its contents are badly corrupted.
