Hello folks, In a current work project, I have inherited a compactPCI board that has an mpc7447/7448 powerpc processor as well as a Marvell system controller, model mv64462 (stripped down mv64460). The board has a somewhat working Gentoo Linux port running on it from long ago and a company far far away (kernel version 2.6.9 built using arch/ppc). To prepare for an upcoming deployment, I would like to bring the OS up-to-date on this board with a newer kernel (targeting Gentoo 2008), but I am unsure of the approach to take. I am a software developer, but normally do not work on kernel porting / board integration. I have researched the arch/ppc to arch/powerpc migration, but I'm a bit intimidated by the 'new' device tree symantics and other changes to the stream. Here are some questions:
1. Is it possible with the 2.6.24 (Gentoo 2008) kernel to still use arch/ppc for this platform architecture? I've tried to get this to compile, but am having trouble with files from arch/powerpc getting pulled in; then I read some comments (from I believe this forum) that indicated that arch/ppc is not longer supposed to compile 2. Does anyone have example code for this platform architecture? Any freebees I could use for creating my device tree? 3. Any advice of any kind? Regards, Stephen
