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

FMC (FPGA Mezzanine Carrier) is a mechanical and electrical
|
|
standard for mezzanine cards that plug into a carrier board.
|
|
This kernel subsystem supports the matching between carrier
|
|
and mezzanine based on identifiers stored in the internal I2C
|
|
EEPROM, as well as having carrier-independent drivers.
|
|
|
|
The framework was born outside of the kernel and at this time
|
|
the off-tree code base is more complete. Code and documentation
|
|
is at git://ohwr.org/fmc-projects/fmc-bus.git .

tristate "FMC fake device (software testing)"

help
|

This is a fake carrier, bringing a default EEPROM content
|
|
that can be rewritten at run time and usef for matching
|
|
mezzanines.

tristate "FMC trivial mezzanine driver (software testing)"
|
|
help
|
|
This is a fake mezzanine driver, to show how FMC works and test it.
|
|
The driver also handles interrupts (we used it with a real carrier
|
|
before the mezzanines were produced)

tristate "FMC mezzanine driver to write I2C EEPROM"
|
|
help
|
|
This driver matches every mezzanine device and can write the
|
|
internal EEPROM of the PCB, using the firmware loader to get
|
|
its binary and the function carrier->reprogram to actually do it.
|
|
It is useful when the mezzanines are produced.

tristate "FMC mezzanine driver that registers a char device"

help
|
|
This driver matches every mezzanine device and allows user
|
|
space to read and write registers using a char device. It
|
|
can be used to write user-space drivers, or just get
|
|
aquainted with a mezzanine before writing its specific driver.
