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
15   instructions with one continuous write and one read for up-to 0xa0
16   bytes. It also supports typical SPI-NAND page cache operations
