I have mpc83xx,

I saw that I need to use swab32 to any read\write operation from registers,
BTW, you should be using in/out_le32() (or for PCI MMIO, readl/writel) 
rather than swab32().  This will be more efficient since it can use the 
lwbrx/stwbrx instructions, and it will keep working even if the code is 
run little-endian.
