2017.1-2017.4 U-boot: spi_flash_probe_bus_cs() failed with KCU105 and AC701 QEMU

Description

I have Booted QEMU to u-boot, then entered the following commands:

U-boot > setenv autotest pm autotest
U-boot > saveenv 

I then receive the following error:

Saving Environment to SPI Flash...

SF: unrecognized JEDEC id bytes: ff, ff, ff

Warning - spi_flash_probe_bus_cs() failed, using default environment
