Just a side note for those who wish to have a second SPI and doesn't have much GPIOs available, NXP has a I2C to SPI bridge, the SC18IS602B.

It is also possible to share the SPI interface used by flash with other devices. There is a sample on bbs.espressif.com that shows how to enable bus arbitration and connect an SPI OLED display.
