7Small Page NAND
8---------------

10The driver uses a 512 byte (1 page) ECC code for this setup. The
11ECC code is not directly compatible with the default kernel ECC
12code, so the driver enforces its own OOB layout and ECC parameters

14Large Page NAND
15---------------
16
17The driver is capable of handling NAND flash with a 2KiB page
18size, with support for hardware ECC generation and correction.
19
20Unlike the 512byte page mode, the driver generates ECC data for
21each 256 byte block in an 2KiB page. This means that more than
22one error in a page can be rectified. It also means that the
23OOB layout remains the default kernel layout for these flashes.
