I'll look into this and report back. The upstream RPi* distributions do not use the linux mainstream *.dts* files but build their own *.dts* files and distribute the resultant *.dtb's directly. For RPi*'s, FreeBSD uses the *.dtb files from some RPI* distribution (via the rpi-firmware port). FreeBSD does not use the linux mainstream *.dts* files for RPi*'s: RPi*'s have a a different compatibility criteria applied compared to most of the Small Arm Boards. So: not in tree. =3D=3D=3D Mark Millard marklmi at yahoo.com
