Re: Call for Testing: Switching back to our BSD licensed dtc(1)

 Hello,

 I've just tried bsd dtc on all arm dts that we have.
 It doesn't seems to handle multiple include directories.
 Here is how to reproduce :

 $ export SRCROOT=/path/to/fbsd/src
 $ export MACHINE=arm
 $ cd $SRCROOT/sys/boot/fdt/dts/arm
 $ $SRCROOT/sys/tools/fdt/make_dtb.sh $SRCROOT/sys
beaglebone-black.dts . converting beaglebone-black.dts
-> ./beaglebone-black.dtb Unable to open file
'/home/elbarto/Work/freebsd/freebsd.git//sys/boot/fdt/dts/arm/am33xx-clocks.dtsi'.
No such file or directory Unable to open file
'/home/elbarto/Work/freebsd/freebsd.git//sys/boot/fdt/dts/arm/tps65217.dtsi'.
No such file or directory

 Both dtsi files are include with /include/ (i.e. not handled by cpp).
 make_dtb.sh specify : -i $S/boot/fdt/dts/${MACHINE} -i
$S/gnu/dts/${MACHINE}, it looks like the second one isn't added to the
list.

 Trying tegra124-jetson-tk1-fbsd.dts give this :
converting tegra124-jetson-tk1-fbsd.dts
-> /tmp/bsd_dtb//tegra124-jetson-tk1-fbsd.dtb Error on line 1214:
Expected node name interrupt-affinity = <&{/cpus/cpu_at_0}>,
                         ^
Error on line 1214: Expected ; at end of property
  interrupt-affinity = <&{/cpus/cpu_at_0}>,
                         ^
Failed to parse tree.  Unhappy face!

 Cheers,
