Prefer not using real our internal hostname / port here. Change it to -DXVC_HOST=xvc_hostname -DXVC_PORT=xvc_port_number

| - `DDEBUG_PROBE`: Selects the debug interface. | ||
| - `DXVC_HOST`: Hostname or IP address of the crate controller running the XVC server. | ||
| - `DXVC_PORT`: TCP port for the XVC server (dafault 2542). | ||
| - `DVERSION`: Specifies the AFC version to be flashed. |

I prefer removing this, these flags are already covered previously.

| This will create a `openocd.cfg` file in `<build_dir>/out`. | ||

| In scenarios where the AFC board is in M7 (Error State) or M1 (Shutdown State), the Xilinx Virtual Cable (XVC) interface is particularly useful, allowing firmware upgrades over Ethernet via JTAG. This enables recovery without physical access to the crate. |

For AFCv4.0 cards, you can program the MMC microcontroller via Xilinx XVC protocol if your MicroTCA crate supports it using the backplane JTAG interface. First, make sure the FPGA is powered off (M1 state), then configure the XVC hostname and port:

| ### OpenOCD | ||
| Flashing the MMC microcontroller via SWD/JTAG is supported for CMSIS-DAP and Jlink compatible probes through OpenOCD. You can specify the debug probe with the flag `-DDEBUG_PROBE=<probe_name>`, valid options are `cmsis-dap` (default), `jlink`, `digilent_jtag_hs3` and `xvc` (support is not merged to the official OpenOCD source yet, so you build our patched version: https://github.com/lnls-dig/openocd/tree/fix-afcv3-flashing). | ||

| You can specify the debug probe in the CMake configuration with the -DDEBUG_PROBE=<probe_name> flag. Example for CMSIS-DAP: |
