- Kernel Versions: 2.6.15.6 ...
"MEM_GRP4_CONFIG"

"SDRAM_GRP1_CONFIG"
- depends on ETRAX_ARCH_V32

"SDRAM_TIMING"
- depends on ETRAX_ARCH_V32
- default "104a"
- 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.
- Option: ETRAX_SDRAM_COMMAND
- Kernel Versions: 2.6.15.6 ...
"SDRAM_COMMAND"
- depends on ETRAX_ARCH_V32

- Option: ETRAX_DEF_GIO_PA_OE
- Kernel Versions: 2.6.15.6 ...
"GIO_PA_OE"
- depends on ETRAX_ARCH_V32
- default "1c"
- Configures the direction of general port A bits. 1 is out, 0 is in. This is often totally different depending on the product used. 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.
