Ji-soo,
I'm using flash on our Integrator platform with 2.4. The CFI layer
understands flash accessing by block and will synchronise accesses
for yo (so long as your device is CFI compliant and most are).
ARM uses a flash partitioning mechanism to break up the flash into
usable lumps - you can add this as a mapping layer. It is not quite
working yet but the functional layering of the flash in 2.4 is very good.
