External topology devices (e.g. PHYs) connected to Columbiaville or to
SoC that includes CPK IP might have a firmware engine within the device
and the firmware is usually loaded from NVM connected to the topology
device.
In some cases, those firmware packages might need to be regularly
updated in a secure way to prevent malicious user to burn malicious
firmware into the topology device. In other cases, the topology device
firmware might be burned independently, as burning the NVM attached to
the device might cause the device to stop function but could be fixed
without permanent damage.
SoC topologies also enable mezzanine card, with an ID EEPROM
within it. This ID EEPROM might need an update also.
This patch provides these abilities.
