1# 2# FMC (ANSI-VITA 57.1) bus support 3# 4 5menuconfig FMC 6 tristate "FMC support" 7 help 8 9 FMC (FPGA Mezzanine Carrier) is a mechanical and electrical 10 standard for mezzanine cards that plug into a carrier board. 11 This kernel subsystem supports the matching between carrier 12 and mezzanine based on identifiers stored in the internal I2C 13 EEPROM, as well as having carrier-independent drivers. 14 15 The framework was born outside of the kernel and at this time 16 the off-tree code base is more complete. Code and documentation 17 is at git://ohwr.org/fmc-projects/fmc-bus.git . 18 19if FMC 20 21config FMC_FAKEDEV 22 tristate "FMC fake device (software testing)" 23 help 24 This is a fake carrier, bringing a default EEPROM content 25 that can be rewritten at run time and usef for matching 26 mezzanines. 27 28config FMC_TRIVIAL 29 tristate "FMC trivial mezzanine driver (software testing)" 30 help 31 This is a fake mezzanine driver, to show how FMC works and test it. 32 The driver also handles interrupts (we used it with a real carrier 33 before the mezzanines were produced) 34 35config FMC_WRITE_EEPROM 36 tristate "FMC mezzanine driver to write I2C EEPROM" 37 help 38 This driver matches every mezzanine device and can write the 39 internal EEPROM of the PCB, using the firmware loader to get 40 its binary and the function carrier->reprogram to actually do it. 41 It is useful when the mezzanines are produced. 42 43config FMC_CHARDEV 44 tristate "FMC mezzanine driver that registers a char device" 45 help 46 This driver matches every mezzanine device and allows user 47 space to read and write registers using a char device. It 48 can be used to write user-space drivers, or just get 49 acquainted with a mezzanine before writing its specific driver. 50 51endif # FMC 52
