[PATCH] Add Broadcom PHY support

This patch adds a driver to support the bcm5421s and bcm5461s PHY

Kernel version:  linux-2.6.18-rc6

Signed-off-by: Amy Fong 

Some 5421's need special initialisation (see drivers/net/sungem_phy.c),
might be worth having them there too. I was also wondering... for
spidernet, we need to enable the fiber mode on the PHY. Does phylib has
an API for that ?

I'd like to look into moving sungem and spidernet over to phylib.

Ben.

I believe that this fiber enabling can be done by defining config_init in the phy_driver struct.

struct phy_driver {
<snip>
        /* Called to initialize the PHY,
	 * including after a reset */
	int (*config_init)(struct phy_device *phydev);
<snip>
};

ie.

static struct phy_driver bcm5421s_driver = {
<snip>
	.config_init = bcm5421s_phy_config,
<snip>
};

int bcm5421s_phy_config(struct phy_device *phydev)
{
...
	/* enable fiber mode here... */
...
}
