Hi,

Our MPC8260 based customs board's flash configuration is as follows

Flash Bank        Base Address                Make                        Number of flashes        per chip size                Total size

CS0                0xFE000000                M29W040B                2                        0.5MB                        1MB
CS1                0xFE800000                AM29LV160BB                2                        2MB                        4MB



My question is

1. Is is mandatory that CS0 and CS1 to be contiguous?
2. what should be the value of  CFG_MAX_FLASH_BANKS? 2 or 4?  
3. If for a board, CS0 has "n1" number of flash chips connected and CS1 has "n2" number of flash chips connected, then what will be the suggested structure of flash driver? I found that flash drivers for different board does not consider the number of physical flash chips present in a board.
4.Is there any reference board which has multiple flash chips connected both to  CS0  and CS1?

Thanks,
Batsayan Das
