* sf: Make 4K sector support configurableMarek Vasut2015-08-17-0/+4
| | | | | | | | | | | | | | | | Make the support for 4K subpage I/O on a SPI NOR flash configurable. A board which requires the SPI NOR to be accessed in larger 32KiB or 64KiB pages can disable the 4K subpage support, but by default, the support for 4K subpage I/O is enabled. The functionality of this option is the same as CONFIG_MTD_SPI_NOR_USE_4K_SECTORS in Linux. This is extremely useful in case one uses UBI on a SPI NOR flash. UBI needs at least 15k EBs and can not work on a flash which uses 4k ones, so disabling the support for 4k subpages lets UBI work on such flash.
