This fixed for me the same issue on my Pinebook Pro, turning

  Loading Environment from SPIFlash... Invalid bus 0 (err=-19)
  *** Warning - spi_flash_probe_bus_cs() failed, using default environment

into

  Loading Environment from SPIFlash... SF: Detected gd25q128 with page size 256 Bytes, erase size 4 KiB, total 16 MiB

Patch attached, for clarity.
