mv643xx_eth: introduce per-port register area pointer
The mv643xx_eth driver uses the rdl()/wrl() macros to read and write hardware registers. Per-port registers are accessed in the following way: #define PORT_STATUS(p) (0x0444 + ((p) << 10)) [...] static inline u32 rdl(struct mv643xx_eth_private *mp, int offset) { return readl(mp->shared->base + offset); } [...] port_status = rdl(mp, PORT_STATUS(mp->port_num)); By giving the per-port 'struct mv643xx_eth_private' its own 'void __iomem *base' pointer that points to the per-port register area, we can get rid of both the double indirection and the << 10 that is done for every per-port register access -- this patch does that.
