	help
	  This option disables all MDIO communication with an ethernet
	  transceiver connected to the MII interface. This option shall
	  typically be enabled if the MII interface is connected to a

	int "Byte-offset of partition table sector"
	depends on ETRAX_AXISFLASHMAP
	default "65536"
	help
	  Byte-offset of the partition table in the first flash chip.
	  The default value is 64kB and should not be changed unless
	  you know exactly what you are doing. The only valid reason
	  for changing this is when the flash block size is bigger
	  than 64kB (e.g. when using two parallel 16 bit flashes).

# While the board info is MMC_SPI only, the drivers are written to be
# independent of MMC_SPI, so we'll keep SPI non-dependent on the
# MMC_SPI config choices (well, except for a single depends-on-line
# for the board-info file until a separate non-MMC SPI board file
# emerges).
# FIXME: When that happens, we'll need to be able to ask for and
# configure non-MMC SPI ports together with MMC_SPI ports (if multiple
# SPI ports are enabled).

config SPI_ETRAX_SSER
