Is the situation such that there is a whole bunch of industrial
systems out there, in active use and needing future upgrades,
that use the EP93xx?  

That's definitely the case. I'm as well aware of several thousands of
industrial devices which are expected to run 24/7 for the next 5
years at least. And they are updated from time to time.

I can agree with this statement.

Arnd has been nudging me to do DT conversion for EP93xx
so if there are many active industrial users of these
I should prioritize it, because these things have 20+ years
support cycles.  

I'm not sure how important or necessary at all is to change anything
in these legacy platforms.

We also need to think about upholding support in GCC for
ARMv4(t) for the foreseeable future if there is a big web of
random deeply embedded systems out there that will need
updates.  

But we should definitely preserve at least what we have.

I'm using OE to build toolchain (SDK). I can confirm that gcc 7.2 works
with it.

And yes, armv4 support shall be preserved in GCC ....
