my cpu is 440gx and my board is OCOTEA.

(1)now i use bootm 0x400000, at the same time,
i set bootargs into console=ttyS0,15200n8 or console=ttySICC,15200n8,
but linux kernel always print little infomation.
i don't know which serial name used.

(2)i use ppc_md.progress as my print function.i find after kernel maps io 
address with ioremap64() and visit the address, kernel die.

ocotea_setup_arch() in the DIR arch/ppc/platforms/4xx/ocotea.c

addr = ioremap64(OCOTEA_MAC_BASE, OCOTEA_MAC_SIZE);
for (i=0; i< 4; i++) {
mac64 = simple_strtoull(addr+OCOTEA_MAC_OFFSET*i, 0, 16);
.......
when the 440gx goes into simple_strtoull, it never returns.
