In this case, i guess you need to apply BUSWIDTH 4 in the
mapping driver and then

   Memory Technology Devices (MTD)  ---> RAM/ROM/Flash chip drivers

should look like this:

   ? ?    [*]   Common Flash Interface (CFI) support
   ? ?    [ ]   CFI Virtual erase regions (EXPERIMENTAL) (NEW)
   ? ?    [*]   CFI Advanced configuration options (NEW)
   ? ?    (NO) Flash cmd/query data swapping
   ? ?    [*]   Specific CFI Flash geometry selection (NEW)
   ? ?    [ ]     Support  8-bit buswidth (NEW)
   ? ?    [ ]     Support 16-bit buswidth (NEW)
   ? ?    [*]     Support 32-bit buswidth (NEW)
   ? ?    [ ]     Support 1-chip flash interleave (NEW)
   ? ?    [*]     Support 2-chip flash interleave (NEW)
   ? ?    [ ]     Support 4-chip flash interleave (NEW)
   ? ?    [ ]     CFI support for Intel/Sharp Basic/Extended Commands
   ? ?    [*]     CFI support for AMD/Fujitsu Standard Commands

And maybe you need to change "Flash cmd/query data swapping"
because auf endianess issues.

hope that helps ...

Bernhard
