S3C24XX NAND Support


Small Page NAND

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

Large Page NAND

The driver is capable of handling NAND flash with a 2KiB page size, with support for hardware ECC generation and correction.

Unlike the 512byte page mode, the driver generates ECC data for each 256 byte block in an 2KiB page. This means that more than one error in a page can be rectified. It also means that the OOB layout remains the default kernel layout for these flashes.
