+-+                          NAND2.0
+-+                ===============================
+-+
+-+    NAND2.0 is a common nand driver which designed for accessing
+-+different type of NANDs(SLC, SPI-NAND, MLC, TLC) on various OS. This
+-+driver can work on mostly SoCs of Mediatek.
+-+
+-+    Although there already has a common nand driver, it doesn't cover
+-+SPI-NAND, and not match our IC-Verification's reqirement. We need
+-+a driver that can be exten or cut easily.
+-+
+-+    This driver is base on NANDX & SLC. We try to refactor structures,
+-+and make them inheritable. We also refactor some operations' flow
+-+principally for adding SPI-NAND support.
+-+
+-+    This driver's architecture is like:
+-+
+-+          Driver @LK/Uboot/DA...           |IC verify/other purposes
+-+    ----------------------------------------------------------------
+-+      partition       |        BBM         |
+-+    -------------------------------------- |       extend_core
+-+             nandx_core/core_io            |
+-+    ----------------------------------------------------------------
+-+             nand_chip/nand_base           |
+-+    -------------------------------------- |        extend_nfi
+-+      nand_device     |    nfi/nfi_base    |
+-+
+-+    Any block of above graph can be extended at your will, if you
+-+want add new feature into this code, please make sure that your code

+-+ * @block_num: the whole block number on the chip
+-+ * @block_size: nand device block size
+-+ * @block_pages: nand device block has page number
+-+ * @page_size: nand device page size

+-+ *    but restricts this:
+-+ *    the size is provied by nand controller(NFI),

+-+ * @min_program_pages: chip needs min pages per program operations

+-+ * @nand: pointer to inherited struct nand_base
+-+ * @read_page: read %count pages on chip
