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.
10 config MTD_SPI_NOR_USE_4K_SECTORS
11 bool "Use small 4096 B erase sectors"
14 Many flash memories support erasing small (4096 B) sectors. Depending
15 on the usage this feature may provide performance gain in comparison
16 to erasing whole blocks (32/64 KiB).
17 Changing a small part of the flash's contents is usually faster with
18 small sectors. On the other hand erasing should be faster when using
19 64 KiB block instead of 16 × 4 KiB sectors.
21 Please note that some tools/drivers/filesystems may not work with
22 4096 B erase size (e.g. UBIFS requires 15 KiB as a minimum).
24 config SPI_FSL_QUADSPI
25 tristate "Freescale Quad SPI controller"
28 This enables support for the Quad SPI controller in master mode.
29 This controller does not support generic SPI. It only supports
33 tristate "NXP SPI Flash Interface (SPIFI)"
34 depends on OF && (ARCH_LPC18XX || COMPILE_TEST)
37 Enable support for the NXP LPC SPI Flash Interface controller.
39 SPIFI is a specialized controller for connecting serial SPI
40 Flash. Enable this option if you have a device with a SPIFI
41 controller and want to access the Flash as a mtd device.
