From: Stephen Warren <redacted> This series adds some build rules to run cpp on *.dts-cpp prior to invoking dtc, and converts Tegra to the new rule as an example. What do people think? I assume that you've applied the dtc patches I sent yesterday. They aren't in this series. See: https://lists.ozlabs.org/pipermail/devicetree-discuss/2012-September/020182.html https://lists.ozlabs.org/pipermail/devicetree-discuss/2012-September/020183.html https://lists.ozlabs.org/pipermail/devicetree-discuss/2012-September/020181.html Note: those patches are against upstream dtc. If you wish to test this series, apply the dtc patches to upstream dtc, build it, and copy the resultant dtc binary over the top of scripts/dtc/dtc. Stephen Warren (3): kbuild: introduce cmd_dtc_cpp ARM: use cmd_dtc_cpp for compilation of *.dts-cpp to *.dtb ARM: tegra: compile all DT files with cpp
Do you have an example of where you'd actually benefit from this? I'd think most things could either be done reasonably well with what's built into DTC (see what we've done in arch/powerpc/boot/dts/fsl), or would need math expression support in DTC (or has that been added?). -Scott
