The specification was changed to reflect a multi-value bad block table. Instead of bit-based bad block table, the bad block table now allows eight bad block categories. Currently four are defined: * Factory bad blocks * Grown bad blocks * Device-side reserved blocks * Host-side reserved blocks The factory and grown bad blocks are the regular bad blocks. The reserved blocks are either for internal use or external use. In particular, the device-side reserved blocks allows the host to bootstrap from a limited number of flash blocks. Reducing the flash blocks to scan upon super block initialization. Support for both get bad block table and set bad block table is added.
