[flashrom] SPI Controller ICH9 Flash driver

[Branham, Paul]

Hello,

We are using your open source flashrom driver for Intel PCH Ibex Peak. (SPI_Controller_ICH9 in the source code with generation>8 => ie. SPIBAR = 0x3800).

The flash ROM driver works well using CS0 by design.

What we are looking for is information on how to use the other chip select -CS1- for some other SPI device. All Intel documentation we have found for this SPI Controller only specifies how to use the Flash capabilities of CS0, but no information whatsoever on how to use CS1 for any other SPI device.

Would you have any source code or other information that may be of help?

Thanks,
- Paul
