OK, so you do all the setup in the boot loader and then the driver just
needs to ioremap() the FPGA? That sounds reasonable and explains why I
haven't found any kernel source code relating to this ...
I just didn't expect the kernel to rely on the boot loader to configure
this. Is that the recommended way to to it?
