Hi !
I noticed you (Stefan) are using request_firmware_nowait() call. This
means user needs to explicitly call it using
$ echo 1 > /sys/class/firmware/lattice-ecp3.0/loading
$ cat lattice-ecp3.bit > /sys/class/firmware/lattice-ecp3.0/data
$ echo 0 > /sys/class/firmware/lattice-ecp3.0/loading
Or did I miss something ?
I would like to have it load the firmware bitstream when booting if
there is a specific .bit file in /lib/firmware. Maybe don't you want
to have this behaviour, though... ?
Thanks,
JM

No, thats correct. This is how we use it on our platform.

No. We don't want this. Please don't ask me about the details. Its quite
a while ago that I worked on this platform. And I don't have access to
this platform any more.
Thanks,
Stefan
