Spartan 7 New Part Support

[kingdipdip]

Hello All!

I am running into issues with adding additional parts to the Spartan 7 Family. Specifically, I am trying to add support for the Spartan xc7s25. I am following the "Guide to adding a new device to an existing family" and am receiving an error when sourcing the new settings file. I am using the baseline "spartan7.sh" to copy setting from and altering XRAY_PART="xc7s50fgga484-1" to XRAY_PART="xc7s25csga324-1" and changing the bounds accordingly. I believe there must be some exception to guide for spartan7, since it is not well supported. I have proceeded with the device.yaml adjustments too.

"xc7s50":
fabric: "xc7s50"
"xc7s25":
fabric: "xc7s25"

Here you can see that the new device is not found. Any assistance with this would be greatly appreciated! I have been troubleshooting this for who knows how long and have not found a solution.

Thanks!
