/* Registers accesible on the DM9000, extracted from pp. 11-12 from the data sheet */

/* There are two interesting addresses for the DM9000
 * (at least in the context of the FriendlyARM MINI2440)
 * The I/O or register select address, which is the base address.
 * The DATA address, which is located at offset 4 from the base address.
 *
 * Chances are that this will not work generally, as it really depends on how the address lines are
 * mapped from the CPU to the DM9000. But for now it is a good starting point.
