+menuconfig FMC
+ tristate "FMC support"
+ help
+
+ 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 .
+
+if FMC
+
+config FMC_FAKEDEV
+ 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.
+
+config FMC_TRIVIAL
+ 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)
+
+config FMC_WRITE_EEPROM
+ 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.
+
+config FMC_CHARDEV
+ 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
+ acquainted with a mezzanine before writing its specific driver.
