+Subject: [PATCH] mtd: spinand: macronix: Add Quad support for serial NAND
+ flash
+
+Adding FLAG "SPINAND_HAS_QE_BIT" for Quad mode support on Macronix
+Serial Flash.
+Validated via normal(default) and QUAD mode by read, erase, read back,
+on Xilinx Zynq PicoZed FPGA board which included Macronix
+SPI Host(drivers/spi/spi-mxic.c).
