Speak to Linaro about their systems, they're nothing to do with me.

Lore provides links to download mboxes FWIW.

OK, so you need a driver or subsystem that implements FPGA updates then
- depending on what that looks like the FPGA or MTD subsystems seem
likely to be candidates, or perhaps the MFD for your device should
provide something as part of the core functionality.  All the issues I
raised earlier apply here, spidev is rarely a good idea for production
use and certainly not in cases where there are actual drivers sharing
the device.

You need to take this up with your mail provider.
