Yeah, I wasn't saying "hey! We need to support old/deprecated cores!".

Oops; my mistake. I've got a trivial patche in my tree that need to be merged for the build to work. I'll get those out ASAP. In the mean time, add "simpleImage%" to the BOOT_TARGETS line in arch/powerpc/Makefile. That will allow you to do: $ make simpleImage.virtex405- where virtex405- corresponds with a file named arch/powerpc/boot/dts/virtex405-.dts Cheers, g. -- Grant Likely, B.Sc., P.Eng.

Grant, could you post explicit instructions about how to build the simpleImage? I tried it too and couldn't get the makefile rules to match my dts. Mike, Supporting mpmc2 for memory access only is pretty straightforward, but supporting the temac/sdma connections is more problematic, particularly since we have no plans to update the plb_temac driver for ARCH=powerpc.

Especially with some of the rc's of late, there have been some simple headaches introduced. So yes, it is because its partially based on a -rc. In simplest terms, I'm getting ready to point-release my product and will have a branch for only maintaining that version of the kernel. It's to avoid things like what happened with the arch/ppc since I started on this ~1 year ago. I needed to rev the kernel from a -rc to a full point-release and then the kernel would boot but crash with real apps running. -- Mike ___ Linuxppc-embedded mailing list Linuxppc-embedded@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-embedded

arch/powerpc, Xilinx, and mainline kernel support
Is there any reason why the mainline 2.6.25.3 (and from what I could see .4) is missing the files to build for the Xilinx Virtex platform? Or in other words, I tried to build from 2.6.25.3 for the Xilinx Virtex under arch/powerpc (because arch/ppc actually crashes when once apps start to run) and it failed when trying to actually create the zImage. I hopped over to Xilinx's git server and noticed a bunch of missing entries in the boot/Makefile and source code to actually support the complete image build for a Xilinx Virtex PPC405. When is the Xilinx Virtex support going to be mainline official? I need to be able to grab a stable kernel and work from there rather than using the latest -rc that Xilinx is hosting on their git server. -- Mike ___ Linuxppc-embedded mailing list Linuxppc-embedded@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-embedded
