Today's main branch comprises a number of GPIO driver improvements that could likely cause boot hangs on certain bords. In order to enable interrupts for SB devices a ICU/GICP rework is needed. Its first working version can be found here: https://reviews.freebsd.org/D28803 however it has to be significantly modified before merge. > > > Was there a pair of FreeBSD - device tree revisions that fully worked? > I modify device tree from the Marvell Linux v4.14.64 > > With above patch whatever is applied on top of the main's sys/contrib/device-tree/src/arm64/marvell/ tree should easily work.
