sorry for bumping this old thread, but I was about to add PRU-ICSSG 
nodes for the phyBOARD-Electra and noticed a difference in the firmware 
names.

Where do these firmware names come from? All references I can find use 
am65x-sr2*: ti-linux-firmware, meta-ti and so on.
Are we expecting the the names to be renamed for linux-firmware?
