Detailed Description
Provides details of a flash bank, available either on-chip or through a major interface.
This structure will be passed as a parameter to the callbacks in the flash_driver_s structure, some of which may modify the contents of this structure of the area of flash that it defines. Driver writers may use the driver_priv member to store additional data on a per-bank basis, if required.
