mtd: spi-nor: Set default Quad Enable method for ISSI flashes
Set the default Quad Enable method for ISSI flashes. Used for ISSI flashes (IS25WP256D-JMLE) that do not support SFDP tables and can not determine the Quad Enable method by parsing BFPT. Based on code originally written by Wesley Terpstra <wesley@sifive.com> and/or Palmer Dabbelt <palmer@sifive.com> https://github.com/riscv/riscv-linux/commit/c94e267766d62bc9a669611c3d0c8ed5ea26569b Signed-off-by: Sagar Shrikant Kadam <sagar.kadam@sifive.com> [tudor.ambarus@microchip.com: - rebase, split and adapt for latest spi-nor/next, - use PMC CFI ID for ISSI. According to JEP106BA, "Programmable Micro Corp" changed its name to Integrated Silicon Solution (ISSI)] Signed-off-by: Tudor Ambarus <tudor.ambarus@microchip.com> Reviewed-by: Vignesh Raghavendra <vigneshr@ti.com>
