I'm running U-Boot 1.3.4 on custom 460EX based board, equipped with 64M P33 flash (similar to Intel P30). See http://www.numonyx.com/Documents/Datasheets/314749_P33_Discrete_DS.pdf
This flash is comprised internally of two 32M flashes.
Then you have to define 2 physical chips in your U-Boot configuration.
I have the following declarations in configuration file:
#define CFG_FLASH_CFI /* The flash is CFI compatible */ #define CFG_FLASH_CFI_DRIVER /* Use common CFI driver */
#define CFG_FLASH_BANKS_LIST {CFG_FLASH_BASE} #define CFG_MAX_FLASH_BANKS 1 /* max number of memory banks */
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.
