I have read it before,but only for module or application,
not for kernel and ppcboot,someone told me because of
ppcboot's relocation,so it is difficult in some externd.
Anyway it helps some:)

Yes,it works:),and I can check thoes regs when entering kernel.
and I am sure ppcboot handle correct value to kernel now.

the kernel can boot and I can see some in the console now.
I replaced the ppcboot.h in the 1.1.6 with one in old version
so I think it is still bdinfo problem.

However,new ones come:
kernel can not find init in the ramdisk!
the initrd had been tested in the old kernel and can mount fs
and entering a little strange:(

the only reason I am wondering is the compiler!
the file in the initrd were compiled with HHL1.2 ppc compiler.
and the kernel was created with eldk.
Is that make sense?
