Subject: Lattice ECP3 FPGA with i.MX6

Hi,

I have a board, with a Freescale i.MX6 chip and a ECP3-35 FPGA on SPI.
I tried to load the firmware using the lattice-ecp3-config driver, but
it fails with this error :

lattice-ecp3 spi32766.3: FPGA bitstream configuration driver registered
lattice-ecp3 spi32766.3: Error: No supported FPGA detected (JEDEC_ID=808004c2)!

In the driver, the id is :

#define ID_ECP3_35 0xc2048080

Obviously, there is a big/little endian issue... Do I need to instruct
the device-tree in a specific way in order to get the bus in the
correct order ? Or is this a known issue maybe ?

Thanks,
JM
