It is definately *used* a lot. It is dubious if it is used with the
latest kernel.
Hartley was/is using it on engraving machinery and using the latest
kernel, I think his setup is pretty large.

The number of deployed machines using EP93xx is likely large, but
more importantly, as with MOXA Art it is likely to be internet connected
and managing vital control systems.

In short: nobody may be upgrading these kernels, but the definately
*should* be upgrading them. For security reasons.

So as a community hat I have concluded it would be socially unacceptable
to delete it and not offer an upgrade path for these systems the
day they realize "oh s.... that is an internet connected pressure boiler".

So if possible it should be modernized.

I would be grateful.
