It's common for multiple steppers to use the same stepper enable
line. Detect this and only create a single digital_out oid on the
micro-controller.
Also, prohibit any other pin from being used multiple times in the
config file.

Update the pressure advance tuning document to note that 0.20 is
likely the ceiling of a useful pressure advance setting.

Try to make the Installation document more friendly to users not
familiar with the Linux command-line. Offer some hints on how to
obtain ssh and how to edit the config file remotely.

Add additional notches and move them to the inside of the square where
they will not impact the outside perimeter test.

Allow the start value to be different from the default/shutdown value
for the pin. This will be useful for "heater fans" that should
startup in the off state, and transition to full on in a shutdown
state.

Pass the sample_ticks and sample_count parameters directly in the
end_stop_home command instead. This simplifies the code.
Also, simplify calculation of next wakeup time in
end_stop_oversample_event().

Place a small notch on one side of the square. The notch provides
interesting information on the extruder performance, and it makes it
easier to compare with previous prints of the object.

Several items were recently implemented. Remove the "cubic vs
quadratic" item as investigations into cubic compression weren't
promising.

Extend the look-ahead mechanism to work between moves that contain Z
movement. This improves Klipper's handling of g-code produced in
"vase mode".

It should no longer be necessary to configure "custom" commands during
mcu setup. The ad5206 and static_digital_output config sections
should provide similar functionality.

Compile the PRU binary with -Os optimization, but request that the
timer dispatch code be compiled with -O2 optimization. This improves
the performance of timers slightly.

The gcc -Os option significantly reduces the size of the PRU binary
and it has little impact on performance.

It is not necessary to limit stepper acceleration - only the limiting

Add a CONFIG_SIMULAVR option to the Kbuild menus and don't directly
prompt users for CONFIG_WATCHDOG or CONFIG_SERIAL_BAUD_U2X. The only
reason to disable these options would be if one were running on
simulavr. This simplifies the user visible menu options.
Also, only show CONFIG_CLEAR_PRESCALER for at90usb1286 chips.
