Inspecting the Makefile.in, I believe that is the case. This is all
there is:
moxie-gdb.dtb: moxie-gdb.dts
dtc -O dtb -o moxie-gdb.dtb ${srcdir}/moxie-gdb.dts
install-dtb: moxie-gdb.dtb
$(SHELL) $(srcdir)/../../mkinstalldirs $(DESTDIR)$(dtbdir)
$(INSTALL_DATA) moxie-gdb.dtb $(DESTDIR)$(dtbdir)/moxie-gdb.dtb
No reference to libraries. I checked the generated moxie-gdb.dtb and it
shows this:
$ file moxie-gdb.dtb
moxie-gdb.dtb: Device Tree Blob version 17, size=519, boot CPU=0, string
block size=75, DT structure block size=388
I am nearly 100% sure this could be a maintainer only option.
FWIW we have been looking into using dtc with RTEMS. It is a nice
way to abstract away the particulars of a SoC and let the BSP/drivers
find their properties from a configuration file/blob during initialization.
But I don't know how this package is distributed.
