| 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 . |

| 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. |

| 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) |

| 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. |

| 46 | This driver matches every mezzanine device and allows user |
