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.

We identify PCI bridges with 'device_type = "pci"' as only PCI bridges should set that property. For bridges, check that node name is pci or pcie, ranges and bus-range are present, and #address-cells and #size-cells are correct. For devices, check the reg property fields are correct for the first element (the config address). Check that the unit address is formatted corectly based on the reg property. Device unit addresses are in the form DD or DD,F where DD is the device 0-0x1f and F is the function 0-7. Also, check that the bus number is within the expected range defined by bridge's bus-ranges.

Since that is always big-endian, it uses fdt64_t elements, which have sparse annotations marking them as not native endian. However, in dtc, we also use struct fdt_reserve_entry inside struct reserve_info, and use it with native endian values. This will cause sparse errors. This stops this abuse, making struct reserve_info have its own native endian fields for the same information. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> /external/dtc/dtc.h

Essentially it contains all the information - in "live" form from a single dts or dtb file. As we move towards support for dynamic dt overlays, that name will become increasingly bad. So, in preparation, rename it to dt_info. At the same time rename the 'the_boot_info' global to 'parser_output' since that's its actual purpose. Unfortunately we do need the global unless we switch to bison's re-entrant parser extensions, which would introduce its own complications.

Fix for_each_*() to check the deleted flag in the loop body every iteration to correct this. Incidentally, this change is why commit 45013d8 dtc: "Add ability to delete nodes and properties" only caused two "make checkm" failures; only two tests actually use multiple labels on the same property or node.

This single level makes it awkward to implement the semantics we want for toggling the checks on the command line.

This automatically converts the tree to dts form (if it's not already) and uses a new "-s" option in dtc to "sort" the tree. That is, it sorts the reserve entries, it sorts the properties within each node by name, and it sorts nodes by name within their parent. This gives a pretty sensible diff between the trees, which will ignore semantically null internal rearrangements (directly diffing the dts files can give a lot of noise due to the order changes).

This is a fairly arbitrary constraint, given that any number of value labels can appear at the same point, and that in C you can have any number of labels on the same statement. This is pretty much a non-issue now, but it may become important with some of the extensions that Grant and I have in mind. It's not that hard to change, so this patch does so, allowing an arbitrary number of labels on any given node or property. As usual a testcase is added too.

329055dbbc3c09e21386ceae788256991f4c8aec	23-Feb-2010	David Gibson <david@gibson.dropbear.id.au>	Disallow re-use of the same label within a dts file Currently, nothing will stop you from re-using the same label string multiple times in a dts, e.g.: / { samelabel: prop1 = "foo"; samelabel: prop2 = "bar"; }; or / { samelabel: prop1 = "foo"; samelabel: subnode { }; }; When using node references by label, this could lead to confusing results (with no warning), and in -Oasm mode will result in output which the assembler will complain about (since it too will have duplicate labels). This patch, therefore, adds code to checks.c to give errors if you attempt to re-use the same label. It treats all labels (node, property, and value) as residing in the same namespace, since the assembler will treat them so for -Oasm mode. Testcases for the new code are also added.

15ad6d862ec7f66dc00783798705a8db1c5d9aca	19-Feb-2010	David Gibson <david@gibson.dropbear.id.au>	dtc: Automatically pick a sensible boot_cpuid_phys Currently, when in -Idts -Odtb or -Ifs -Odtb modes, dtc always defaults to using 0 as the value for the boot_cpuid_phys header field. That's correct quite often, but there are some systems where there is no CPU with hardware ID of 0, or where we don't want to use the CPU with hardware ID 0 at all (e.g. for AMP-style partitioning). The only way to override this default currently, is with the -b command line option. This patch improves dtc to instead base the default boot_cpuid_phys value on the reg property of the first listed subnode of /cpus. This means that dtc will get boot_cpuid_phys correct by default in a greater proportion of cases (since the boot cpu is usually listed first, and this way at least the boot_cpuid_phys default will match some existing cpu node). If the node doesn't exist or has an invalid 'reg' property (missing or not 4 bytes in length), then boot_cpuid_phys is set to 0.

We eliminate the current clunky mechanism which combines search paths (which we don't actually use at present) with the open relative to current source file behaviour, which we do. Instead there's a single srcfile_relative_open() entry point for callers which opens a new input file relative to the current source file (which the srcpos code tracks internally). It doesn't currently do search paths, but we can add that later without messing with the callers, by drawing the search path from a global (which makes sense anyway, rather than shuffling it around the rest of the processing code). That suffices for non-dts input files. For the actual dts files, srcfile_push() and srcfile_pop() wrappers open the file while also keeping track of it as the current source file for future opens.

d75b33af676d0beac8398651a7f09037555a550b	26-Nov-2009	David Gibson <david@gibson.dropbear.id.au>	Support ePAPR compliant phandle properties Currently, the Linux kernel, libfdt and dtc, when using flattened device trees encode a node's phandle into a property named "linux,phandle". The ePAPR specification, however - aiming as it is to not be a Linux specific spec - requires that phandles be encoded in a property named simply "phandle". This patch adds support for this newer approach to dtc and libfdt. Specifically: - fdt_get_phandle() will now return the correct phandle if it is supplied in either of these properties - fdt_node_offset_by_phandle() will correctly find a node with the given phandle encoded in either property. - By default, when auto-generating phandles, dtc will encode it into both properties for maximum compatibility. A new -H option allows either only old-style or only new-style properties to be generated. - If phandle properties are explicitly supplied in the dts file, dtc will not auto-generate ones in the alternate format. - If both properties are supplied, dtc will check that they have the same value. - Some existing testcases are updated to use a mix of old and new-style phandles, partially testing the changes. - A new phandle_format test further tests the libfdt support, and the -H option.

This patch switches dtc over to using the libfdt macros (including libfdt_env.h to supply them).

As well as being a totally unuseful default value, this also means that dtc won't properly preserve the boot_cpuid_phys field in -I dtb -O dtb mode. This patch reworks things to improve the boot_cpuid handling. The new semantics are that the output's boot_cpuid_phys value is: the value given on the command line if -b is used otherwise the value from the input, if in -I dtb mode otherwise 0 Implementation-wise we do the following: - boot_cpuid_phys is added to struct boot_info, so that structure now contains all of the blob's semantic information. - dt_to_blob() and dt_to_asm() output the cpuid given in boot_info - dt_from_blob() fills in boot_info based on the input blob - The other dt_from_*() functions just record 0, but we can change this easily if e.g. we invent a way of specifying the boot cpu in the source format. - main() overrides the cpuid in the boot_info between input and output if -b is given We add some testcases to check this new behaviour.

It used to be that main() would open the input based on command line arguments before passing it to the dt_from_() function. However, only dt_from_blob() uses this. dt_from_source() opens its own file, and dt_from_fs() interprets the argument as as a directory and does its own opendir() call. Furthermore, main() opened the file with dtc_open_file() but closed it with a direct call to fclose(). Therefore, to improve the interface consistency between the dt_from_() functions, make dt_from_blob() open and close its own files like the other dt_from_*() functions.

For one thing, this test has, for no good reason, three different ways for those functions to communicate a failure to provide input (bi NULL, bi->dt NULL, or bi->error non-zero). For another, in every case save one, if the dt_from_() functions are unable to provide input they will immediately die() (with a more specific error message) rather than proceeding to the test in main(). Therefore, this patch removes this test, making the one case that could have triggered it (in dt_from_source()) call die() directly instead. With this change, the error field in struct boot_info is now unused, so remove it. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> /external/dtc/dtc.h

That's long gone, since the lifetime issues were far more trouble than it was worth, so get rid of the asize field. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> /external/dtc/dtc.h

This patch simplifies flattree.c by making -I dtb mode use fill_fullpaths() like the others. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> /external/dtc/dtc.h

Previously, only failure to parse caused the reading of the tree to fail; semantic errors that called yyerror() but not YYERROR only emitted a message, without signalling make to stop the build.

376ab6f2ed5aac107ef197ff2ec401bf2a8239bd	18-Dec-2007	David Gibson <david@gibson.dropbear.id.au>	dtc: Remove remaining old-style checks The remaining old-style tree checking code: check_root(), check_cpus() and check_memory() really aren't that useful. They mostly check for the presence of particular nodes and properties. That's inherently prone to false-positives, because we could be dealing with an artificial tree (like many of the testcases) or it could be expected that the missing properties are filled in by a bootloader or other agent. If any of these checks really turns out to be useful, we can reimplement them later in a better conceived way on top of the new checking infrastructure. For now, just get rid of them, removing the last vestiges of the old-style checking code (hoorah). Signed-off-by: David Gibson <david@gibson.dropbear.id.au> /external/dtc/dtc.h

Such references are expanded to the full path of the referenced node, as a string, instead of to a phandle as references within cell lists are evaluated. A testcase is also included.
