2012-11-21script: dtc: clean generated filesMagnus Damm
Fix "make distclean" to clean up generated dtc files. Without this patch the following files are left around: - dtc-lexer.lex.c - dtc-parser.tab.c - dtc-parser.tab.h Signed-off-by: Magnus Damm <damm@opensource.se> Reviewed-by: Simon Horman <horms@verge.net.au> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2012-10-17dtc: fix for_each_*() to skip first object if deletedStephen Warren
The previous definition of for_each_*() would always include the very first object within the list, irrespective of whether it was marked deleted, since the deleted flag was not checked on the first object, but only on any "next" object. Fix for_each_*() to check the deleted flag in the loop body every iteration to correct this.

2012-10-01dtc: import latest upstream dtcStephen Warren
This updates scripts/dtc to commit 317a5d9 "dtc: zero out new label objects" from git://git.jdl.com/software/dtc.git. This adds features such as: * /bits/ syntax for cell data. * Math expressions within cell data. * The ability to delete properties or nodes. * Support for #line directives in the input file, which allows the use of cpp on *.dts. * -i command-line option (/include/ path) * -W/-E command-line options for error/warning control. * Removal of spew to STDOUT containing the filename being compiled. * Many additions to the libfdt API.

2011-01-03of/flattree: Update dtc to current mainline.John Bonesio
Pull in recent changes from the main dtc repository. These changes primarily allow multiple device trees to be declared which are merged by dtc. This feature allows us to include a basic dts file and then provide more information for the specific system through the merging functionality.

during a check of the current git head of the linux kernel with the static code analysis tool cppcheck (http://sourceforge.net/apps/mediawiki/cppcheck/index.php?title=Main_Page) the tool discovered a resource leak in linux-2.6/scripts/dtc/fstree.c.

2009-05-02Move dtc and libfdt sources from arch/powerpc/boot to scripts/dtcDavid Gibson
The powerpc kernel always requires an Open Firmware like device tree to supply device information. On systems without OF, this comes from a flattened device tree blob. This blob is usually generated by dtc, a tool which compiles a text description of the device tree into the flattened format used by the kernel. Sometimes, the bootwrapper makes small changes to the pre-compiled device tree blob (e.g. filling in the size of RAM). To do this it uses the libfdt library. Because these are only used on powerpc, the code for both these tools is included under arch/powerpc/boot (these were imported and are periodically updated from the upstream dtc tree). However, the microblaze architecture, currently being prepared for merging to mainline also uses dtc to produce device tree blobs. A few other archs have also mentioned some interest in using dtc. Therefore, this patch moves dtc and libfdt from arch/powerpc into scripts, where it can be used by any architecture. The vast bulk of this patch is a literal move, the rest is adjusting the various Makefiles to use dtc and libfdt correctly from their new locations.
