Where i have to add num_ssrs=0. If I add it into .hal there is a error "unknown command".
 
You added it to config string?
Code:
loadrt hm2_rpspi config="num_ssrs=0"

Yes, I tried it also in the hm2_rpspi config string.
The message is here " invalid token in config string: "num_ssrs=0" "

Is there any manual where the ssr funktionality is explained? 
The output in the HAL Configuration says that hm2_7c80.0.ssr.00.out-01 is off (yellow) All other outputs are red.
The hardware switches all outputs to high.

It bug in hostmot2 driver(hostmot2.c: hm2_parse_config_string()), no code for reading "num_ssrs=" value.
Affected 2.8 and 2.9, in 2.7 hostmot2 driver not support ssr.
Fix code:
Code:
        } else if (strncmp(token, "num_ssrs=", 9) == 0) {             token += 9;             hm2->config.num_ssrs = simple_strtol(token, NULL, 0);

Yes that was missed because there is no actual hardware where
disabling SSRs makes sense . For the OPs use, 7C80 firmware with no SSRs
makes more sense

Oh.
What I have to do if i have to compile linuxcnc with fixed driver?
Follow this  steps?

Can anybody make a bit File with following Pinout (IOPort<=>Pin from 7c80spi.ucf)?

Out0..7 in phase with AC Ref == on and Out0..7 out of phase with AC Ref == off. The only logical for following hardware is a XOR chip. We never have seen sth like this and i cannot find sth about it.

It makes zero sense to change the driver, you need to make a
bitfile that matches your hardware.

If you take the pinout file that D.L. provided and edit it to:

1. Add your additional encoders, sserial ports and PWMgens
2. Remove the inmux (actually not sure here if your hardware include the muxes or not)

Either D.L or I can take that new pinout and make a bitfile that
matches your hardware.

2. Remove the inmux (actually not sure here if your hardware include the muxes or not)
 
1. Additional encoders, sserial ports and PWMgens not needed, the pinout was created for the current scheme .
2. InMux module needed, in the current scheme used multiplexing(ICs: U1-U4) input signals IN0-IN23.
