# FMC (ANSI-VITA 57.1) bus support
#
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.
