25 minutes is really quite scary. And user will see no notification
other than "Installing 50%" for 25 minutes? And will most likely not 
be able to do anything that'd involve talking to the FW, like setting
port info/speed?

Is it possible for the FW to inform that it's updating the CPLD?

Can you release the dev_cmd_lock periodically to allow other commands
to be executed while waiting?
