I just did this last week. My test load is cooking in the test oven now. You need to tickle the WD at several places within the kernel. For me, it worked by putting the tickle code in kernel/sched.c & arch/ppc/boot/simple/misc-embedded.c. Granted, there is likely a better place to put chip spec

PPC440GP Support

Hi, we are designing a custom PPC440GP Board right now, and would like to know the status of the Linux port. When (roughly estimated) and how will it be possible to get a first version supporting the IBM Eboni evaluation board? Best regards, Stefan Roese ** Sent via the linuxppc-embedded mail

Hi everybody I tried to boot a FADS860T board with the 2.4.18 linux kernel, and experienced problems with cache set in Copy-Back mode. The kernel configuration help states that you can say 'Y' to Copy-Back mode if 'you don't know what that is about', so that's what I did. I then got a 'kernel a
