This patchset adds Dynamic DT support in the DTC compiler as used in a number of boards like the beaglebone/rpi/chip and others. The first patch passes a boot_info argument instead of the root node to the check methods. The second patch documents the internals of overlay generation, while the third one adds dynamic object/overlay support proper. The last patch simply adds a few overlay tests verifying operation. This patchset is against DTC mainline and is also available for a pull request from https://github.com/pantoniou/dtc/tree/overlays Regards -- Pantelis Changes since v9: * Reversed -M switch to by default use new DTBO magic value. * Removed global versionflags in the parser by using inherited attributes. * build_node instead of malloc at add_orphan_node(). * Do not use escape for path copy * Do not generate /plugin/ when generating a dts file even when the plugin flag is set.. Changes since v8: * Removed extra member of boot_info in each node; passing boot_info parameter to the check methods instead. * Reworked yacc syntax that supports both old and new plugin syntax * Added handling for new magic number (enabled by 'M' switch). * Dropped dtbo/asmo formats. * Added overlay testsuite. * Addressed last version maintainer comments. Changes since v7: * Dropped xasprintf & backward compatibility patch * Rebased against dgibson's overlay branch * Minor doc wording fixes. Changes since v6: * Introduced xasprintf * Added append_to_property and used it * Changed some die()'s to assert * Reordered node generation to respect sort * Addressed remaining maintainer changes from v6 Changes since v5: * Rebase to latest dtc version. * Addressed all the maintainer requested changes from v5 * Added new magic value for dynamic objects and new format Changes since v4: * Rebase to latest dtc version. * Completely redesigned the generation of resolution data. Now instead of being generated as part of blob generation they are created in the live tree. * Consequently the patchset is much smaller. * Added -A auto-label alias generation option. * Addressed maintainer comments. * Added syntactic sugar for overlays in the form of .dtsi * Added /dts-v1/ /plugin/ preferred plugin form and deprecate the previous form (although still works for backward compatibility) Changes since v3: * Rebase to latest dtc version. Changes since v2: * Split single patch to a patchset. * Updated to dtc mainline. * Changed __local_fixups__ format * Clean up for better legibility.
