Issue with uboot 2016.2 and QSPI

Hi,

I am running custom Linux 4.4 on a Picozed with a custom carrier.

I have recently upgraded to U-boot 2016.2 from 2015.2 and have attempted to make the transition from the config based setup to the devicetreein u-boot.

I have come across this issue:

U-Boot 2016.01-dirty (Sep 06 2016 - 16:24:18 +1200)

Model: Zynq PicoZed Board
Board: Xilinx Zynq
DRAM:  ECC disabled 0 Bytes
MMC:   sdhci@e0100000: 0, sdhci@e0101000: 1
*** Warning - spi_flash_probe() failed, using default environment

In:    serial@e0000000
Out:   serial@e0000000
Err:   serial@e0000000
Model: Zynq PicoZed Board
Board: Xilinx Zynq
Net:   ZYNQ GEM: e000b000, phyaddr 0, interface rgmii-id
eth0: ethernet@e000b000
Hit any key to stop autoboot: 0
Copying Linux from QSPI flash to RAM...
Failed to initialize SPI flash at 0:0 (error -2)

------------------

----

Anyone able to help? Is there anything obvious I am doing wrong?

Thanks,

Tim
