Hi,

The Programmable Real-Time Unit Industrial Communication Sub-system (PRU-ICSS)
is available on the TI SOCs in two flavors: Gigabit ICSS (ICSSG) and the older
Megabit ICSS (ICSSM).

Support for ICSSG Dual-EMAC mode has already been mainlined [1] and the
fundamental components/drivers such as PRUSS driver, Remoteproc driver,
PRU-ICSS INTC, and PRU-ICSS IEP drivers are already available in the mainline
Linux kernel. The current RFC patch series builds on top of these components
and introduces changes to support the Dual-EMAC mode on ICSSM, especially on
the TI AM57xx devices.

I guess this version also has the horrible architecture of multiple
firmware's you need to swap between at runtime?

This series has support for a single protocol. Yes, swapping of firmwares will be required upon adding support for other protocols similar to ICSSG. 

Thanks & Best Regards,
Basharath
