From: David Andrey david.andrey@netmodule.com
Avoid overwriting GEMx_RCLK_CTRL and GEMx_CLK_CTRL if the Ethernet interface is connect on EMIO
Do not enable emio for this standard board configuration for now.
Signed-off-by: David Andrey david.andrey@netmodule.com Signed-off-by: Michal Simek michal.simek@xilinx.com --- Changes in v2: - Remove CONFIG_ prefix from non configurable macros (emio)
