Then you have to define 2 physical chips in your U-Boot configuration.

This will not work. Take a look at the lwmon5 configuration. It has a similar
Intel FLASH which has two chips inside:
#define CFG_FLASH0 0xFC000000
#define CFG_FLASH1 0xF8000000
#define CFG_FLASH_BANKS_LIST { CFG_FLASH1, CFG_FLASH0 }
#define CFG_MAX_FLASH_BANKS 2
...
You need to change the addresses for your 32MB version though.
Hope this helps.
