ADSP-SC589-EZKIT: Update SPI Flash from Linux (Standard mode)

I would like to raw write (not using jffs2) spi flash from Linux.

As per dts file, the flash is configured to use 4 rx lines (SPI Quad mode).


Instead of Quad SPI mode, I would like to access the flash in standard SPI mode (1 RX line) as I have other SPI slaves on the SPI bus. 


How can I configure spi flash in standard mode? Just change "spi-rx-bus-width" to 1 in dts file is enough or are there other settings as well?
