In this mode, the controller can perform 1-bit spi-mem ops for up-to 0xa0 bytes and typical SPI-NAND single, dual and quad IO page cache ops with 2-byte address. Additionally, the page cache ops can be performed with ECC and auto data formatting using the ECC engine of the controller. This patchset implements support of this mode as a separated SPI-MEM driver with piplined ECC engine.
