Hi,
I'm working on IBM Ebony board and trying to make linux running on it. I built a linux-2.6.10 (from kernel.org) image but somehow the kernel refused to pick up the bootargs because the kernel command linux shows nothing and ethernet address is all 0xFF. I've researched DULG and this mailing list and got some hints that this is usually caused by the kernel's unawareness of uboot's bd_info.
However adding #include <asm/ppcboot.h> in arch/ppc/platforms/4xx/ibm440gp.h doesn't help solve the problem. I must have missed something else. What am I missing here?
