Currently it only exposes a read only access to the entire 8K bits efuse memory and the ethernet mac address for the davicom dm9000 chip on the CI20 board. It also changes the nemc reg range to avoid overlap. Tested-by: Mathieu Malaterre Signed-off-by: PrasannaKumar Muralidharan Signed-off-by: Mathieu Malaterre Signed-off-by: H.
