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 help This enables support for the Quad SPI controller in master mode. We only connect the NOR to this controller now. endif # MTD_SPI_NOR
