20 Waitstates for flash. The default value is suitable for the
21 standard flashes used in axis products (120 ns).
23 config ETRAX_MEM_GRP2_CONFIG
25 depends on ETRAX_ARCH_V32
28 Waitstates for SRAM. 0 is a good choice for most Axis products.
30 config ETRAX_MEM_GRP3_CONFIG
32 depends on ETRAX_ARCH_V32
35 Waitstates for CSP0-3. 0 is a good choice for most Axis products.
36 It may need to be changed if external devices such as extra
37 register-mapped LEDs are used.
39 config ETRAX_MEM_GRP4_CONFIG
41 depends on ETRAX_ARCH_V32
44 Waitstates for CSP4-6. 0 is a good choice for most Axis products.
46 config ETRAX_SDRAM_GRP0_CONFIG
47 hex "SDRAM_GRP0_CONFIG"
48 depends on ETRAX_ARCH_V32
51 SDRAM configuration for group 0. The value depends on the
52 hardware configuration. The default value is suitable
53 for 32 MB organized as two 16 bits chips (e.g. Axis
54 part number 18550) connected as one 32 bit device (i.e. in
57 config ETRAX_SDRAM_GRP1_CONFIG
58 hex "SDRAM_GRP1_CONFIG"
59 depends on ETRAX_ARCH_V32
62 SDRAM configuration for group 1. The default value is 0
63 because group 1 is not used in the default configuration,
64 described in the help for SDRAM_GRP0_CONFIG.
66 config ETRAX_SDRAM_TIMING
68 depends on ETRAX_ARCH_V32
71 SDRAM timing parameters. The default value is ok for
72 most hardwares but large SDRAMs may require a faster
73 refresh (a.k.a 8K refresh). The default value implies
74 100MHz clock and SDR mode.
76 config ETRAX_SDRAM_COMMAND
78 depends on ETRAX_ARCH_V32
81 SDRAM command. Should be 0 unless you really know what
82 you are doing (may be != 0 for unusual address line
83 mappings such as in a MCM)..
85 config ETRAX_DEF_GIO_PA_OE
87 depends on ETRAX_ARCH_V32
90 Configures the direction of general port A bits. 1 is out, 0 is in.
91 This is often totally different depending on the product used.
92 There are some guidelines though - if you know that only LED's are
93 connected to port PA, then they are usually connected to bits 2-4
94 and you can therefore use 1c. On other boards which don't have the
95 LED's at the general ports, these bits are used for all kinds of
96 stuff. If you don't know what to use, it is always safe to put all
97 as inputs, although floating inputs isn't good.
99 config ETRAX_DEF_GIO_PA_OUT
101 depends on ETRAX_ARCH_V32
104 Configures the initial data for the general port A bits. Most
105 products should use 00 here.

109 depends on ETRAX_ARCH_V32
112 Configures the direction of general port B bits. 1 is out, 0 is in.

121 config ETRAX_DEF_GIO_PB_OUT
123 depends on ETRAX_ARCH_V32
126 Configures the initial data for the general port B bits. Most
127 products should use 00000 here.

149 products should use 00000 here.
151 config ETRAX_DEF_GIO_PD_OE
153 depends on ETRAX_ARCH_V32
156 Configures the direction of general port D bits. 1 is out, 0 is in.
157 This is often totally different depending on the product used.
158 There are some guidelines though - if you know that only LED's are
