There are other Xscale CPUs. Is the memsetup.S generic enough to support them as well. I don't know the answer to this yet. I will be porting u-boot to IXP420 in the next few weeks and will have a better idea. Maybe someone else already knows.
My impression is that at the moment everything that's labled "XScale" in u-boot is "PXA" in reality, so an audit has to be done anyway.
Do you have information about how the memory controller of the IXP is different from the PXAs?
Actually, the mem controller is completely different. The IXP has separate SDRAM and expansion buses. Most other parts of cpu/xscale will be different as well (e.g., interrupt.c, serial.c). It may be that we need to have ixp and pxa subdirs. We can leave xscale (really pxa) as is, move memsetup there, and create a new ixp.
