	---help---
	  If you have a network (Ethernet) card belonging to this class, say Y
	  and read the Ethernet-HOWTO, available from
	  <http://www.tldp.org/docs.html#howto>.

	  Note that the answer to this question doesn't directly affect the
	  kernel: saying N will just cause the configurator to skip all
	  the questions about ARC cards. If you say Y, you will be asked for
	  your specific card in the following questions.

	  On some legacy ARC (Synopsys) FPGA boards such as ARCAngel4/ML50x
	  non-standard on-chip ethernet device ARC EMAC 10/100 is used.
	  Say Y here if you have such a board.  If unsure, say N.

	select ARC_EMAC_CORE

	---help---
	  Support for Rockchip RK3066/RK3188 EMAC ethernet controllers.
	  This selects Rockchip SoC glue layer support for the
	  emac device driver. This driver is used for RK3066/RK3188
	  EMAC ethernet controller.
