Hi, I want to port a board ( WRS SBC8265 ) from the PPC branch to the POWERPC branch in the Linux Kernel -- do you have any good starting points that describes what I need to pay attention to? I've already made a port of U-boot-1.3.1 and enabled CONFIG_OF_LIBFDT. So I need to create a DTS file, compile it with the DTC compiler and port the current PPC branch to the POWERPC branch to my understanding. Cheers // Matias

Yes, you're exactly right. Use one of the dts files in arch/powerpc/boot/dts as a starting point and read Documentation/powerpc/booting-without-of.txt to find out what is expected in the device tree. Cheers, g. -- Grant Likely, B.Sc., P.Eng. Secret Lab Technologies Ltd.

Is there any more information on how the "of_*" ( e.g. of_node_put , of_find_node_by_type ) functions should be implemented in the "arch/powerpc/platforms/myplatform/myboard_setup.c" file or is the documentation the existing "*.c" c files under arch/powerpc/platforms ? Since I have a 82xx board I assume that "myboard_setup.c" file shall be put under arch/powerpc/platforms/82xx. Cheers // Matias Grant Likely skrev:

Maybe. Which 82xx is it? There is a notable difference between, say, the 824x boards and the 827x boards. If it is the latter, perhaps the existing 82xx/ pq2 or mpc8272 parts are already sufficient? If it is the former group, 824x, perhaps some of the parts in embedded6xx/ are usable? Also note that I am working on publishing an 824x StorCenter port under embedded6xx/ at this time as well. First patches were posted to linuxppc-dev list at ozlabs.org. HTH, jdl

Not all 824x fall into that category; for example, 8248 is pq2. Someone in marketing should be shot. -Scott

Gah. Of course.

The board is based on PPC8265. Cheers // Matias
