so, limit switches and home switches were not there to begin with.
//////////////////////////////////////////
is this what need to add for limit switches
###
### Sample separate limit switches on the X axis (axis 0)
###
net X-neg-limit parport.0.pin-11-in => axis.0.neg-lim-sw-in
net X-pos-limit parport.0.pin-12-in => axis.0.pos-lim-sw-in
/////////////////////////////////////////////
and for home
### A sample home switch on the X axis (axis 0). make a signal,
### link the incoming parport pin to the signal, then link the signal
### to LinuxCNC??s axis 0 home switch input pin
###
net Xhome parport.0.pin-10-in => axis.0.home-sw-in
###
Approximately right but you are not using a parallel port
so the pin names of the hardware side will be different something more like:
net Xhome axis.0.home-sw-in <= hm2_[HOSTMOT2](BOARD).0.gpio.048.in_not
Note that the gpio number (the 048) depends on which 5I20 connector the
7I37 is connected to and which 7I37 input the limit switch connects to.
(the 048 is just an example)

Because some integrators will want switches and some will not.
It is a SAMPLE configuration. It can never be perfect for everyone.
You are the integrator, you are expected to look at the samples and
learn enough to modify them to suit your own needs.
