Detailed Description

This structure contains information about the flash device on the board.

    The bblist points to an array of bytes where each position represents a
    block on the device. If the block is good it is marked as 0xFF. If the block
    is bad, it is marked as 0x00. For devices that do not support a bad block list this
    value will be NULL. The number of blocks in the bblist is determined by the block_count field.
