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