mtd: spi-nor: Add Freescale QuadSPI driver (0) What is the QuadSPI controller? The QuadSPI(Quad Serial Peripheral Interface) acts as an interface to one single or two external serial flash devices, each with up to 4 bidirectional data lines. (1) The QuadSPI controller is driven by the LUT(Look-up Table) registers. The LUT registers are a look-up-table for sequences of instructions. A valid sequence consists of four LUT registers. (2) The definition of the LUT register shows below: --------------------------------------------------- | INSTR1 | PAD1 | OPRND1 | INSTR0 | PAD0 | OPRND0 | --------------------------------------------------- There are several types of INSTRx, such as: CMD : the SPI NOR command. ADDR : the address for the SPI NOR command. DUMMY : the dummy cycles needed by the SPI NOR command. .... There are several types of PADx, such as: PAD1 : use a singe I/O line. PAD2 : use two I/O lines. PAD4 : use quad I/O lines. .... (3) Test this driver with the JFFS2 and UBIFS: For jffs2: ------------- #flash_eraseall /dev/mtd0 #mount -t jffs2 /dev/mtdblock0 tmp #bonnie++ -d tmp -u 0 -s 10 -r 5 For ubifs: ------------- #flash_eraseall /dev/mtd0 #ubiattach /dev/ubi_ctrl -m 0 #ubimkvol /dev/ubi0 -N test -m #mount -t ubifs ubi0:test tmp #bonnie++ -d tmp -u 0 -s 10 -r 5 Signed-off-by: Huang Shijie <b32955@freescale.com> Signed-off-by: Brian Norris <computersforpeace@gmail.com>

obj-$(CONFIG_MTD_MT81xx_NOR) += mtk-quadspi.o
mtd: spi-nor: add driver for NXP SPI Flash Interface (SPIFI) Add SPI-NOR driver for the SPI Flash Interface (SPIFI) controller that is found on newer NXP MCU devices. The controller supports serial SPI Flash devices with 1-, 2- and 4-bit width in either SPI mode 0 or 3. The controller can operate in either command or memory mode. In memory mode the Flash is exposed as normal memory and can be directly accessed by the CPU.
