|
| 30 | - running
|
| 31 | - For boards where the management function is split between multiple
|
| 32 | control units, this is the CMC control unit's firmware version.
|
| 33 | * - ``fpga.rev``
|
| 34 | - running
|
| 35 | - FPGA design revision.
|
| 36 | * - ``fpga.app``

|
| 63 | Flash Update
|
| 64 | ============
|
| 65 |
|
| 66 | The ``sfc`` driver implements support for flash update using the
|
| 67 | ``devlink-flash`` interface. It supports updating the device flash using a
|
| 68 | combined flash image ("bundle") that contains multiple components (on ef10,
|
| 69 | typically ``fw.mgmt``, ``fw.app``, ``fw.exprom`` and ``fw.uefi``).
|
| 70 |
|
| 71 | The driver does not support any overwrite mask flags.
