7 title: SPI-NAND flash controller for MediaTek ARM SoCs
10 - Chuanhong Guo <gch981213@gmail.com>
13 The Mediatek SPI-NAND flash controller is an extended version of
14 the Mediatek NAND flash controller. It can perform standard SPI
15 instructions with one continuous write and one read for up-to 0xa0
16 bytes. It also supports typical SPI-NAND page cache operations
17 in single, dual or quad IO mode with pipelined ECC encoding/decoding
18 using the accompanying ECC engine. There should be only one spi
