Federico Vaga 9c0dda1495 drivers/fmc: carrier can program FPGA on registration
The initial FPGA may require programming before it is useful.

Federico Vaga 15b1b0f0d8 drivers/fmc: change registration prototype
Permit use of either fmc_device_register_n or fmc_device_register_n_gw
depending on the type of device in use.

Federico Vaga 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)

Federico Vaga 9f757f4152 drivers/fmc: hide fmc operations behind helpers
This gave us more freedom to change/add/remove operations without
recompiling all device driver.

Typically, Carrier board implement the fmc operations, so they will not
use these helpers.

Alessandro Rubini 5c9a87367d FMC: make eeprom attribute writable
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.

Alessandro Rubini e4d6c4b79c FMC: support carriers with no mezzanine
At registration and unregistration time, I was checking fmc->flags
for FMC_DEVICE_NO_MEZZANINE, to skip initialization and cleanup for
empty slots.  The check was wrong ("==" instead of "&") but
registration failed anyways (as expected) because we had no EEPROM.

This commit fixes one such checks and removes the other, so to
actually accept slots with no mezzanines. That's because the carrier
may offer some support anyways (the SPEC does), and working on the
carrier with no mezzanine-specific driver is common during
development.

Alessandro Rubini 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.
