BTW if that can help, I already have a working port of the driver that is
present in Marvell's kernel. The port is absolutely ugly, it's plain copy
paste of the HAL parts that I needed until it built and booted. It worked
on my mirabox with 3.8. I know it doesn't work since recently (I believe
since introduction of the mbus driver) though I haven't had time to check
why yet. The advantage of such an ugly work is that I'm sure that it will
never be merged into mainline :-)
