2071a3e94a drivers/fmc: The only way to dump the SDB is from debugfs
Driver should not call fmc_sdb_dump() anymore. (actually they can but the
operation is not supported, so it will print an error message)

4debfe409b FMC: add a char-device mezzanine driver
This driver exports the memory area associated with the mezzanine card
as a misc device, so users can access registers.

6007b1bd0f FMC: add a driver to write mezzanine EEPROM
This driver allows to reprogram the EEPROM in a mezzanine, to store
its own identifiers during manufacturing or to save other useful data.

056d83f3c3 FMC: add a software mezzanine driver
This simple do-nothing mezzanine driver shows how to write a mezzanine
driver, that can also handle interrupts reported by the carrier.

6c62a895e5 FMC: add a software carrier driver
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.

77864f2e0a FMC: add core bus driver
This module offers registration services for both carriers
(i.e. devices) and mezzanines (i.e. drivers). The matching for devices
and drivers is performed according to the IPMI standard for FRU
devices (Field Replaceable Units).

The code includes support for parsing an SDB tree if present in the FPGA,
and dumping it for diagnostics. SDB is not mandatory.

Files in this commit correspond to commit ab23167f in the master branch
of the project hosted on ohwr.org.

9c9f32edde FMC: create drivers/fmc and toplevel Kconfig question
This commit creates the drivers/fmc directory and puts the necessary
hooks for kbuild and kconfig.  The code is currently a placeholder
that only registers an empty bus.
