Yes devicetree was invented as a way for embedded powerpc systems to provide the same information to the kernel as openfirmware (IEEE 1275) already provided on server and desktop powerpc machines. That system was already in use on powerpc and sparc machines. I can't remember if any MIPS machines used openfirmware or not. The fact FCODE on add in PCI cards and similar could be used to initialize and enumerate devices in the system is quite nice since it is CPU architecture independant (It is Forth code). -- Len Sorensen -- To UNSUBSCRIBE, email to debian-arm-requ...@lists.debian.org with a subject of "unsubscribe".
