Block Device driver uses a buffer so we need to ensure data is written or read to the device and not to the buffer so we can be sure if the device works properly
To define an N way split this define the following:
#define BOARD_HAS_MTD_PARTITION_OVERRIDE {"/fs/mtd_params", "/fs/mtd_waypoints","/fs/equal_part" }
OR
To define a percentage split this define the following:
#define BOARD_HAS_MTD_PARTITION_OVERRIDE {"/fs/mtd_params", "/fs/mtd_waypoints","/fs/tiny" }
#define BOARD_MTD_PARTITION_TABLE_SIZES {50.0f, 49.0f, 1.0f}
