Thank you for contacting us.
As far as I know, the pins will be the same if you haven't modify the BIOS. I'm not sure if Ubuntu have the SPI drivers, but you can test these pins and let us know if it works
Have a nice day.
Regarding SPI and UBUNTU,
There is mention that Intel requires an NDA, how do I request the NDA such that I can be provided with additional resources/docs/tools to access SPI for UBUNTU?
I'm afraid it's a private bug. The outcome, though, is that Intel has a tool to enable SPI, but is not yet ready to release it without an NDA. You might consider talking to them. – Kyle
