2 tristate "SPI-NOR device support"
5 This is the framework for the SPI NOR which can be used by the SPI
6 device drivers and the SPI-NOR device driver.
11 tristate "Mediatek MT81xx SPI NOR flash controller"
13 This enables access to SPI NOR flash, using MT81xx SPI NOR flash
14 controller. This controller does not support generic SPI BUS, it only
15 supports SPI NOR Flash.
17 config MTD_SPI_NOR_USE_4K_SECTORS
18 bool "Use small 4096 B erase sectors"
21 Many flash memories support erasing small (4096 B) sectors. Depending
22 on the usage this feature may provide performance gain in comparison
23 to erasing whole blocks (32/64 KiB).
24 Changing a small part of the flash's contents is usually faster with
25 small sectors. On the other hand erasing should be faster when using
26 64 KiB block instead of 16 × 4 KiB sectors.
28 Please note that some tools/drivers/filesystems may not work with
29 4096 B erase size (e.g. UBIFS requires 15 KiB as a minimum).
31 config SPI_FSL_QUADSPI
32 tristate "Freescale Quad SPI controller"
33 depends on ARCH_MXC || COMPILE_TEST
36 This enables support for the Quad SPI controller in master mode.
37 This controller does not support generic SPI. It only supports
41 tristate "NXP SPI Flash Interface (SPIFI)"
42 depends on OF && (ARCH_LPC18XX || COMPILE_TEST)
45 Enable support for the NXP LPC SPI Flash Interface controller.
47 SPIFI is a specialized controller for connecting serial SPI
48 Flash. Enable this option if you have a device with a SPIFI
49 controller and want to access the Flash as a mtd device.
