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() ?

Is this MPC7448 anything like an mpc7448hpc2 ?

If so maybe you should start by looking at the code for it in:

arch/powerpc/platforms/embedded6xx/mpc7448_hpc2.c

Even if it's not related, that will give you some idea of what the
callbacks are for.
