SPEAr: Place ethaddr write and read within CONFIG_CMD_NET
ethaddr can be optionally read from i2c memory. So, chip_config command supports reading/writing hw mac id into i2c memory. Placing this code within CONFIG_CMD_NET as this would only be needed when network interface is configured Signed-off-by: Vipin Kumar <vipin.kumar@st.com> Signed-off-by: Amit Virdi <amit.virdi@st.com> Signed-off-by: Stefan Roese <sr@denx.de>
