Embedded MPC860T & flash memory

[Laurent Pinchart]

Hi everybody,

I'm developping a custom MPC860T board, and need 16MB of flash memory.

As I need to be able to write to the memory using the MTD layer, I was
wondering if it would be better to use 2 16-bit wide chips in
interleaved mode on a 32-bit bus (connecting them in parallel to the
bus, one of them storing D[0:15] and the other one D[16:31]), or to use
them in non-interleaved mode (non-overlapping address ranges) on a
16-bit bus. It seems that the Linux MTD layer can support both
configurations, but I don't have a deep knowledge of that code, and thus
would appreciate any advice.

I'll probably use AMD devices.

Thanks in advance for your help.
