On the boards at91sam9260ek, at91sam9263ek and afed9260, the rstc register was set to 0 after being set to 500 ms for the PHY reset. Do backup the old reset length and restore it after the MACB initialisation. Signed-off-by: Sedji Gaouaou <sedji.gaouaou@atmel.com> Signed-off-by: Stelian Pop <stelian@popies.net>
