I'd recommend to use blocks normally, but secors for one block (using one or more sectors to store the U-Boot envrionment). For such a configuration, CFG_MAX_FLASH_SECT = 47 would be correct.
Yes. But keep in mind: If you sometime want to use bigger flash's with more sectors (blocks) you will have to increase this setting!
No! You have to configure the maxmium sector count with this define (and _not_ the sector-size!). Most of the time I set this to 256. This should sufficient for most flash's.
Stefan: as you can see, this is actually a bad advice, as it would be wrong here.
OK, since we use these SST flash's alway in block mode I forgot about the sector mode.
By the way: Erase time is not a real issue with the SST flash's. Even chip erase is done in a few ms.
