1==================== 2S3C24XX NAND Support 3==================== 4 5Introduction 6------------ 7 8Small Page NAND 9--------------- 10 11The driver uses a 512 byte (1 page) ECC code for this setup. The 12ECC code is not directly compatible with the default kernel ECC 13code, so the driver enforces its own OOB layout and ECC parameters 14 15Large Page NAND 16--------------- 17 18The driver is capable of handling NAND flash with a 2KiB page 19size, with support for hardware ECC generation and correction. 20 21Unlike the 512byte page mode, the driver generates ECC data for 22each 256 byte block in an 2KiB page. This means that more than 23one error in a page can be rectified. It also means that the 24OOB layout remains the default kernel layout for these flashes. 25 26 27Document Author 28--------------- 29 30Ben Dooks, Copyright 2007 Simtec Electronics
