Depending 15 on the usage this feature may provide performance gain in comparison 16 to erasing whole blocks (32/64 KiB). 17 Changing a small part of the flash's contents is usually faster with 18 small sectors. On the other hand erasing should be faster when using 19 64 KiB block instead of 16 × 4 KiB sectors. 20 21 Please note that some tools/drivers/filesystems may not work with 22 4096 B erase size (e.g. UBIFS requires 15 KiB as a minimum). 23 24config SPI_FSL_QUADSPI 25 tristate "Freescale Quad SPI controller" 26 depends on ARCH_MXC 27 help 28 This enables support for the Quad SPI controller in master mode. 29 We only connect the NOR to this controller now. 30 31endif # MTD_SPI_NOR 32
