menuconfig MTD_SPI_NOR
tristate "SPI-NOR device support"
depends on MTD
help
This is the framework for the SPI NOR which can be used by the SPI
device drivers and the SPI-NOR device driver.
if MTD_SPI_NOR
config MTD_SPI_NOR_USE_4K_SECTORS
bool "Use small 4096 B erase sectors"
default y
help
Many flash memories support erasing small (4096 B) sectors. Depending
on the usage this feature may provide performance gain in comparison
to erasing whole blocks (32/64 KiB).
Changing a small part of the flash's contents is usually faster with
small sectors. On the other hand erasing should be faster when using
64 KiB block instead of 16 × 4 KiB sectors.
Please note that some tools/drivers/filesystems may not work with
4096 B erase size (e.g. UBIFS requires 15 KiB as a minimum).
config SPI_FSL_QUADSPI
tristate "Freescale Quad SPI controller"
depends on ARCH_MXC || COMPILE_TEST
depends on HAS_IOMEM
help
This enables support for the Quad SPI controller in master mode.
This controller does not support generic SPI. It only supports
SPI NOR.
config SPI_NXP_SPIFI
tristate "NXP SPI Flash Interface (SPIFI)"
depends on OF && (ARCH_LPC18XX || COMPILE_TEST)
depends on HAS_IOMEM
help
Enable support for the NXP LPC SPI Flash Interface controller.
SPIFI is a specialized controller for connecting serial SPI
Flash. Enable this option if you have a device with a SPIFI
controller and want to access the Flash as a mtd device.
config ASPEED_FLASH_SPI
tristate "Aspeed flash controllers in SPI mode"
depends on HAS_IOMEM && OF
depends on ARCH_ASPEED || COMPILE_TEST
# IO_SPACE_LIMIT must be equivalent to (~0UL)
depends on !NEED_MACH_IO_H
help
This enables support for the New Static Memory Controller (FMC)
in the AST2400 when attached to SPI nor chips, and support for
the SPI Memory controller (SPI) for the BIOS.
