Hmmm, your config works for me on a POWER6 partition here, whether I
netboot the zImage.pseries or boot it with yaboot. I wonder if your

The mpc7448hpc2 uses a tsi108-bridge. My board uses an IP on a FPGA.. I read
the code of mpc7448_hpc2.c.
It uses a ioremap in order to iniatilize the tsi108 registers. But I have
already initialized MMU with my registers in HEAD_32.S. Do I need to use
ioremap in setup_arch() ?
