Using Intel's SPI controller driver

[khm]

Hi, we'd like to read the contents of the platform's SPI flash. Where do I find documentation on how to use the interface exposed by the Intel SPI Flash controller that's shipped with Windows? For reference my development platform is a C620 series PCH running Windows 11.

Hey Sergio,
