2017-07-13dtc: change default phandles to ePAPR style instead of bothRob Herring
Currently, both legacy (linux,phandle) and ePAPR (phandle) properties are inserted into dtbs by default. The newer ePAPR style has been supported in dtc and Linux kernel for 7 years. That should be a long enough transition period. We can save a little space by not putting both into the dtb.

Add an fdtoverlay unit test. Applies applies overlay(s) and then retrieves an inserted property to verify. Signed-off-by: Pantelis Antoniou <pantelis.antoniou@konsulko.com> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
2017-06-15fdtoverlay: A tool that applies overlaysPantelis Antoniou
Since libfdt support overlay application on FDT blobs, provide a command line tool that applies an arbitrary number of overlays, one after another to a base fdt blob and output the result in the given file.

2017-06-08dtc: fix sprintf() format string error, againDavid Gibson
2a42b14 "dtc: check.c fix compile error" changed a format string using %lx which wasn't correct for all platforms. Unfortunately it changed it to %zx, which is wrong for a different set of platforms (and only right on the others by accident). The parameter we're formatting here is uint64_t, not size_t, so we need to use the PRIx64 macro from <inttypes.h> to get this right. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
2017-05-20Makefile: Fix build on MSYS2 and CygwinCufi, Carles
The host compiler on MSYS2 and Cygwin does not allow the -fPIC option, issuing a warning that is treated as an error and stops the build. Detect whether we're running under MSYS2 or Cygwin and avoid adding -fPIC to prevent the error from happening. Tested on Linux, MSYS2 and Cygwin.

2017-05-17Suppress expected error message in fdtdump testDavid Gibson
Since 548aea2 "fdtdump: Discourage use of fdtdump", fdtdump unconditionally prints a message discouraging its own use except for debugging purposes. This shows up messily in the "make check" output, so suppress it. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

2017-04-19Fix get_node_by_path string equality checkTim Montague
When determining if to recurse into a node, get_node_by_path does not check if the length of each node name is equal. If searching for /foo/baz, this can result in recursing into /foobar because strneq("foo", "foobar", 3) is true. This can result in a reference to /foo/baz to be incorrectly set to /foobar/baz. A test for this was added. Signed-off-by: Tim Montague <tmontague@ghs.com> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

2017-04-18fdtdump: Discourage use of fdtdumpDavid Gibson
fdtdump is, and always has been, a quick-and-dirty debugging tool. However I keep getting reports of people using it for real work. For production decompiling of a dtb, dtc in -I dtb -O dts mode is the right tool. In the hopes of getting that message out there, add a warning message to fdtdump to discourage its use. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
2017-04-18fdtdump: Fix over-zealous version checkDavid Gibson
It's perfectly valid for a dtb to have version and last compat version set to the same value, and that value can be 17 (the latest defined version). However, since 0931cea "dtc: fdtdump: check fdt if not in scanning mode" fdtdump will refuse to process such a dtb. We get away with this in many cases because dtc's typical output has last compat version equal to 16, rather than 17, but it's still a bug. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

2017-04-08pylibfdt: Allow setup.py to operate stand-aloneSimon Glass
At present we require that setup.py is executed from the Makefile, which sets up various important things like the list of files to build and the version number. However many installation systems expect to be able to change to the directory containing setup.py and run it. This allows them to support (for example) building/installing for multiple Python versions, varying installation paths, particular C flags, etc. The problem in implementing this is that we don't want to duplicate the information in the Makefile. A common solution (so I am told) is to parse the Makefile to obtain the required information. Update the setup.py script to read a few Makefiles when it does not see the required information in its environment. This allows installation using: ./pylibfdt/setup.py install Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>

2017-04-02Add a libfdt function to write a property placeholderSimon Glass
The existing function to add a new property to a tree being built requires that the entire contents of the new property be passed in.
