In our SoC current architecture there are multiple sdio buses, basically 
one for each MAC.
Neverthelees this architecture might change in the future.

Moreover, I agree that driver should be generic, so I guess that we 
might add a phy_addr field
in the device structure and pass it thru the initialize routine, as the 
macb driver is doing.

In the meantime I saw that Vipin already provided a V2 of the driver, 
which is still in the old
way.
Vipin, can you possibly provide your comments?

Thanks,
Arm
