Are you 100% sure these are arranged as 4 8-bit devices side-by-side on the 
32-bit bus? It's more common in my experience to have 2 devices together in 
16-bit mode, and to have two such pairs consecutively mapped in the address 
space if there are four chips.

Turn off CONFIG_MTD_CFI_ADV_OPTIONS and let it try all the probes.
