I/O mapping strategy of RRF is being reviewed because the next generation Duet needs something more flexib

Sounds great! I got some more pins I'd like to remap, I'll wait and see what you guys churn out.

Hey, first time poster, long time user/lurker.

I've been trying to use E4 endstop connector as a ZProbe input and couldn't find a clean way to do it so went ahead and added a new param to M558.

The reasoning behind this is that I'm using a custom board on the expansion port for my specific machine.

Here's the PR https://github.com/dc42/RepRapFirmware/pull/191
I've tried to keep Mode 4 and Mode 6 default behavior if the user don't pass the new E params. Latest commit should handle all the cases.

One other thing I looked into was remapping specific IO pins from config files, but haven't had the time/brain to code anything yet.

I wasn't sure if github was monitored for PR, but if this shouldn't be there do not hesitate to delete my thread.
