Hi padudle,
Is this your post here on the Xilinx forums?

It looks like the latest xilinx_devcfg driver can handle non byte reversed bitstreams.

Perhaps there is something going wrong with the bitstream during your write_cfgmem step to swap the endianness? Have you already tried to load a non byte reversed bitstream under 4.6 kernel?
Regards,
