+Firmware Versions
+-----------------
+
+fbnic has three components stored on the flash which are provided in one PLDM
+image:
+
+1. fw - The control firmware used to view and modify firmware settings, request
+ firmware actions, and retrieve firmware counters outside of the data path.
+ This is the firmware which fbnic_fw.c interacts with.
+2. bootloader - The firmware which validate firmware security and control basic
+ operations including loading and updating the firmware. This is also known
+ as the cmrt firmware.
+3. undi - This is the UEFI driver which is based on the Linux driver.
+
+fbnic stores two copies of these three components on flash. This allows fbnic
+to fall back to an older version of firmware automatically in case firmware
+fails to boot. Version information for both is provided as running and stored.
+The undi is only provided in stored as it is not actively running once the Linux
+driver takes over.
+
+devlink dev info provides version information for all three components. In
+addition to the version the hg commit hash of the build is included as a
+separate entry.
