I am porting a custom mpc8xx board . using PPCBOOT + MontaVista Linux 2.1(2.4.17). I found that if I set IMMR to 0x12200000 in PPCBOOT and Linux. The linux kernel can startup,but will stop in exece("/sbin/init").I use a bdi2000 and found that it deadloop in do_page_fault. But if I set IMMR to 0xFF000000, the linux kernel can work good. I think this limitation must be somewhere in the arch/ppc/kernel/head_8xx.S.right?
