This allows easier modification to the eeprom than loading the
fmc-write-eeprom module. The carrier driver will refuse writing if
the FPGA is not running the golden gateware image, so writing in
practice is only available at manufacture/development time.

This driver exports the memory area associated with the mezzanine card
as a misc device, so users can access registers.

This driver allows to reprogram the EEPROM in a mezzanine, to store
its own identifiers during manufacturing or to save other useful data.

This simple do-nothing mezzanine driver shows how to write a mezzanine
driver, that can also handle interrupts reported by the carrier.

This fake carrier is designed to help FMC users understand how a
carrier driver works, and to experiment the behaviour with EEPROM
reprogramming (with a mezzanine driver commited later). This carrier
can register up to 4 (fake) mezzanines.
We have real carriers (both on PCI-E and VME), but they are bigger
things and are not part of this submission.
