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"
14 This enables access to SPI NOR flash, using MT81xx SPI NOR flash
15 controller. This controller does not support generic SPI BUS, it only
16 supports SPI NOR Flash.
18 config MTD_SPI_NOR_USE_4K_SECTORS
19 bool "Use small 4096 B erase sectors"
22 Many flash memories support erasing small (4096 B) sectors. Depending
23 on the usage this feature may provide performance gain in comparison
24 to erasing whole blocks (32/64 KiB).
25 Changing a small part of the flash's contents is usually faster with
26 small sectors. On the other hand erasing should be faster when using
27 64 KiB block instead of 16 × 4 KiB sectors.
29 Please note that some tools/drivers/filesystems may not work with
30 4096 B erase size (e.g. UBIFS requires 15 KiB as a minimum).
32 config SPI_FSL_QUADSPI
33 tristate "Freescale Quad SPI controller"
34 depends on ARCH_MXC || SOC_LS1021A || ARCH_LAYERSCAPE || COMPILE_TEST
37 This enables support for the Quad SPI controller in master mode.
38 This controller does not support generic SPI. It only supports
42 tristate "NXP SPI Flash Interface (SPIFI)"
43 depends on OF && (ARCH_LPC18XX || COMPILE_TEST)
46 Enable support for the NXP LPC SPI Flash Interface controller.
48 SPIFI is a specialized controller for connecting serial SPI
49 Flash. Enable this option if you have a device with a SPIFI
50 controller and want to access the Flash as a mtd device.
