This completes the show_sdb_tree functionality, with the
new informative fields. The output for a verbose module is now

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.Signed-off-by: Alessandro Rubini

The code reported wrong addresses in the sdb dumps. All sdb addresses
are relative, but the code was adding the base address twice. Bug
exposed by a gateware image with two bridge levels.Thanks David for reporting the problem.

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.Signed-off-by: Alessandro Rubini

The fmc-chardev module was over-locking, by calling misc
register/unregister while holding its spinlock. This reported a
"scheduling while atomic" error.Since the misc driver already serializes operations internally, this
commit downgrades the fmc-chardev lock to just cover its own list.Reported-by: Sasha Levin

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.Signed-off-by: Alessandro Rubini

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.Signed-off-by: Alessandro Rubini
