This controller does not support generic SPI BUS, it only 16 supports SPI NOR Flash. 17 18config MTD_SPI_NOR_USE_4K_SECTORS 19 bool "Use small 4096 B erase sectors" 20 default y 21 help 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. 28 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). 31 32config SPI_FSL_QUADSPI 33 tristate "Freescale Quad SPI controller" 34 depends on ARCH_MXC || SOC_LS1021A || ARCH_LAYERSCAPE || COMPILE_TEST 35 depends on HAS_IOMEM 36 help 37 This enables support for the Quad SPI controller in master mode. 38 This controller does not support generic SPI.
