Maybe, because most boards will then need 2 flashs with different
interfaces. Afaik only the Atmel at91... can boot directly from serial
dataflash due to it's internal ROM services.
Even this seems to be not a mainstream way to boot, because the
maintainer of the available bootloader (u-boot) declared that way to
boot deprecated.
In our case it was fine, because this allowed to reduce the size of the
board.
Another reason might be a hen/egg problem. (driver/first board available)
Best regards
Peter
