I would like to investigateif we can do this using runtime detection instead of a separate config option. Give me some days. The runtime detection can be done reading the sysboot configuration for example. I think it's possible, do you think would be possible ?
Until we have the device model and the ability to see at run-time if we have say NAND or OneNAND (or neither!) we can't because we have to build-time define where the environment will be found.

Hi Enric,
Runtime detection is possible reading the sysboot as you said (in fact this is how we do it in the kernel) but as Tom said I didn't find a common way to do this. I guess you can manually detect the NAND type and configure the GPMC registers on the board code but I didn't see other OMAP boards doing this. Instead I found other examples of boards using compile options to choose between memory types.
Of course I will be more than glad if you have a better approach to solve this :-)
Thanks a lot and best regards, Javier
