//  This file contains information about NAND flash used on H4Sample board.
//  There are two group of constants. First defines READY/~BUSY signal and it
//  is board specific. Second defines NAND geometry and it depends on chip
//  used.

//  Following constats must be specified for each supported NAND chip:
//  1. manufacturer ID (UINT8), 2. device Id (UINT8), 
//  3. number of block (UINT32), 4. sectors per block (UINT32),
//  5. sector data size (UINT32), 6. extended address (BOOL)
