readl()/writel() are defined to access PCI memory space in units of 32
bits. PCI is by definition little-endian, PowerPC is (natively at
least) big-endian, hence the byt

I have been working on a driver for a PowerPC PCI card/framebuffer device,
and noticed that the standard readl() and writel() for this platform to
byte swapping, since PowerPC runs big-endian. However, at least for my
hardware it's *really* not needed, and should just do a regular load
