FMC: Staticize local symbols

2013-08-12T22:45:40Z

This local symbol is used only in this file. Fix the following sparse warnings: drivers/fmc/fmc-write-eeprom.c:106:5: warning: symbol 'fwe_probe' was not declared. Should it be static? drivers/fmc/fmc-write-eeprom.c:147:5: warning: symbol 'fwe_remove' was not declared. Should it be static?

FMC: fix locking in sample chardev driver

2013-07-25T05:56:52Z

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.

FMC: fix error handling in probe() function

2013-06-24T23:23:25Z

The call to kzalloc() wasn't checked. The dev_info() message dereferenced freed memory on error. Signed-off-by: Dan Carpenter Acked-by: Alessandro Rubini Signed-off-by: Greg Kroah-Hartman

fmc: avoid readl/writel namespace conflict

2013-06-20T03:30:32Z

The use of the 'readl' and 'writel' identifiers here causes build errors on architectures where those are macros. This renames the fields to read32/write32 to avoid the problem.

FMC: NULL dereference on allocation failure

2013-06-20T03:30:31Z

If we don't allocate "arr" then the cleanup path will dereference it and oops. Signed-off-by: Dan Carpenter Acked-by: Alessandro Rubini Signed-off-by: Greg Kroah-Hartman

FMC: add a char-device mezzanine driver

2013-06-18T22:42:15Z

This driver exports the memory area associated with the mezzanine card as a misc device, so users can access registers. Signed-off-by: Alessandro Rubini Acked-by: Juan David Gonzalez Cobas Acked-by: Emilio G. Cota Acked-by: Samuel Iglesias Gonsalvez Signed-off-by: Greg Kroah-Hartman

FMC: add a driver to write mezzanine EEPROM

2013-06-18T22:42:15Z

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

FMC: add a software mezzanine driver

2013-06-18T22:41:04Z

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

FMC: add a software carrier driver

2013-06-18T22:41:04Z

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.

FMC: add core bus driver

2013-06-18T22:36:56Z

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 Acked-by: Juan David Gonzalez Cobas Acked-by: Emilio G.
