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_ASPEED_SMC 33 tristate "Aspeed flash controllers in SPI mode" 34 depends on ARCH_ASPEED || COMPILE_TEST 35 depends on HAS_IOMEM && OF 36 help 37 This enables support for the Firmware Memory controller (FMC) 38 in the Aspeed AST2500/AST2400 SoCs when attached to SPI NOR chips, 39 and support for the SPI flash memory controller (SPI) for 40 the host firmware.
