cmd_mdio.c: In function 'mdio_read_ranges': cmd_mdio.c:97: warning: comparison is always false due to limited range of data type Signed-off-by: Anatolij Gustschin <agust@denx.de> Cc: Andy Fleming <afleming@freescale.com>
2011-04-20Add mdio command for new PHY infrastructureAndy Fleming
The new mdio command doesn't have all of the features of the mii command, but it provides the necessary read/write primitives, and allows users to interact with 10G PHYs, and other PHYs which use Clause 45 of 802.3. This means that the mdio command requires a "Device Address" argument, though for clause 22 PHYs, the argument can be "-".
