This controller does not support generic [31mCONFIG_SPI[0m BUS, it only supports [31mCONFIG_SPI[0m NOR Flash. config [31mCONFIG_MTD_SPI_NOR_USE_4K_SECTORS[0m bool "Use small 4096 B erase sectors" default y help Many flash memories support erasing small (4096 [31mCONFIG_B[0m) 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 [31mCONFIG_B[0m erase size (e.g. UBIFS requires 15 KiB as a minimum). config [31mCONFIG_SPI_ATMEL_QUADSPI[0m tristate "Atmel Quad SPI Controller" depends on [31mCONFIG_ARCH_AT91[0m || ([31mCONFIG_ARM[0m && [31mCONFIG_COMPILE_TEST[0m) depends on [31mCONFIG_OF[0m && [31mCONFIG_HAS_IOMEM[0m help This enables support for the Quad [31mCONFIG_SPI[0m controller in master mode.
