We've have been using a 2.6.16.18 kernel (from TimeSys) up until now, and I hacked in some crude support for no-phy configs forced to 100Mbit and 1Gbit speeds. Now I'm moving to 2.6.22 (with 8360 the patches from bitshrine.org), and I'm trying to understand how I should do this with device trees, the new PHY infrastructure, etc. Has anyone else needed this support? Does anyone have any suggestions as to how to tackle it? check out the fixed-link property and associated code. This implementation came about after 2.6.22 though (it's commit-ish v2.6.23-10096-ga21e282). Kim Thanks for the pointer Kim! Using the fixed-link property code already in the tree, and adding the glue in ucc_geth.c to use it (modeled after the code in gianfar fix-link support in fsl_soc.c), I was able to get this working with me 8360 board. Is there a document anywhere that describes how to submit patches for the powerpc kernel?Or do I just create the patch (I'm learning about git right now...) again the paulus/powerpc.git tree, and send it to this list?

Correct. Don't just lean toward git, actually use it. And paulus/powerpc.git is the right basis.

Kernel oops in MPC8568MDS BSP
Hello, I am using MPC8568MDS BSP on my board, which has same memory map as MPC8568MDS board has. However I have kernel oops at free_bootmem_with_active_regions() within do_init_bootmem(). Any idea on this issue? Thanks, Mike bootm 0x100 0x200 0x40 ## Booting image at 0100 ...
