I don't know of any working Marvel 64260 or 64360 code in this time frame. I do know that the 64360 was patched to mainline at ~2.6.13. Since then all real Marvel work should have been done on mainline. I'd reccommend moving forward. > > > >Not being familiar with the gt64260 Ethernet device or > >code, I plan to take it line by line. That is probably a mistake for a number of reasons. First, you will not be able to get this into the mainline because it does not use the platform_device structures like the Marvell 64360 ethernet device. Secondly, most of the developers doing Marvell work, are using the 64360 chipset. I'd reccommend using a newer kernel and backporting the 64360 ethernet code to 64260. I just looked at my baseline tree (2.6.12-rc1) and see the only platform using the 64260 chip, besides the eval board, was the cpci690.c. I would look and see ifthis is still a working platform and base your platform code off of that.

In the kernel.org tree the MPSC driver is working along with the 360 ethernet device. > Note the the mpsc > driver that's there still isn't working correctly. I haven't loked at the 64260 for well over a year since we went to the 64360. The 260 was just too bad in too many respects. I was willing to test the 260 code with my old hardware if there was a merged driver and even develop the merged driver, but it became obvious the merged driver was going to be ugly Thanks Brian
