You need to configure the CS1 EBC settings in your config header correctly for
this:
#define CONFIG_SYS_EBC_PB1AP your-values
#define CONFIG_SYS_EBC_PB1CR ...
And then add the 2nd FLASH chip to the FLASH list in the same config header.
Something like this:
#define CONFIG_SYS_FLASH_BANKS_LIST { 0xfc000000, 0xfe000000 }
Cheers,
Stefan
