Is there a good method of setting up two flash devices at once? As far as I can tell, all the flash functions (like flash_print_info, for example) can only be defined for one type of flash at a time.
You can use the addresses to differentiate which flash device are accessed. Keep the same interfaces uboot has already had and just develop your own functions to do the actual jobs.
The other option might be to create my own flash function wrappers that call the appropriate flash function based on, for example, the address passed into the function.
That's what I did before on a EP8245 board. This way shields all the differences.
Shawn,
In that case, did both flash devices use the same driver? My two flash devices use different drivers. So what I am currently doing is adding a prefix to the different flash driver functions (ie: change CFI's write_buff to cfi_write_buff) and then adding function pointers to each flash bank structure indicating which function to use.
This seems to be a decent approach. The main problem is that the flash calls are a bit scattered, and also it will require all flash devices to be changed. But I'll continue with it unless someone has a better solution?
