Similarly, firmware is very often unlikely to be updated. So we need to
support situations where we use old firmware with new kernels. The cuImage
support is a classic example of this. Moving code from kernel to firmware
just because some people think it belongs in the firmware is usually impractical.
If we added code to U-Boot today to configure the par_io pins, it would
probably still be years before we could safely remove that code from the kernel.
