	  Waitstates for CSP0-3. 0 is a good choice for most Axis products.

	depends on ETRAX_ARCH_V32
	default "336"
	help
	  SDRAM configuration for group 0. The value depends on the
	  hardware configuration. The default value is suitable
	  for 32 MB organized as two 16 bits chips (e.g. Axis
	  part number 18550) connected as one 32 bit device (i.e. in
	  the same group).

config ETRAX_SDRAM_GRP1_CONFIG
	hex "SDRAM_GRP1_CONFIG"
	depends on ETRAX_ARCH_V32
	default "0"
	help
	  SDRAM configuration for group 1. The default value is 0
	  because group 1 is not used in the default configuration,
	  described in the help for SDRAM_GRP0_CONFIG.

config ETRAX_SDRAM_TIMING
	hex "SDRAM_TIMING"

	default "104a"
	help
	  SDRAM timing parameters. The default value is ok for
	  most hardwares but large SDRAMs may require a faster
	  refresh (a.k.a 8K refresh). The default value implies
	  100MHz clock and SDR mode.

config ETRAX_SDRAM_COMMAND
	hex "SDRAM_COMMAND"
	depends on ETRAX_ARCH_V32
	default "0"

	  SDRAM command. Should be 0 unless you really know what

	  There are some guidelines though - if you know that only LED's are
	  connected to port PA, then they are usually connected to bits 2-4
	  and you can therefore use 1c.  On other boards which don't have the
	  LED's at the general ports, these bits are used for all kinds of
	  stuff.  If you don't know what to use, it is always safe to put all
	  as inputs, although floating inputs isn't good.
