This controller does not support generic SPI BUS, it only 15 supports SPI NOR Flash. 16 17config MTD_SPI_NOR_USE_4K_SECTORS 18 bool "Use small 4096 B erase sectors" 19 default y 20 help 21 Many flash memories support erasing small (4096 B) sectors. Depending 22 on the usage this feature may provide performance gain in comparison 23 to erasing whole blocks (32/64 KiB). 24 Changing a small part of the flash's contents is usually faster with 25 small sectors. On the other hand erasing should be faster when using 26 64 KiB block instead of 16 × 4 KiB sectors. 27 28 Please note that some tools/drivers/filesystems may not work with 29 4096 B erase size (e.g. UBIFS requires 15 KiB as a minimum). 30 31config SPI_FSL_QUADSPI 32 tristate "Freescale Quad SPI controller" 33 depends on ARCH_MXC || COMPILE_TEST 34 depends on HAS_IOMEM 35 help 36 This enables support for the Quad SPI controller in master mode. 37 This controller does not support generic SPI.
