menuconfig SFI bool "SFI (Simple Firmware Interface) Support" ---help--- The Simple Firmware Interface (SFI) provides a lightweight method for platform firmware to pass information to the operating system via static tables in memory. Kernel SFI support is required to boot on SFI-only platforms. Currently, all SFI-only platforms are based on the 2nd generation Intel Atom processor platform, code-named Moorestown.

For more information, see http://simplefirmware.org

Say 'Y' here to enable the kernel to boot on SFI-only platforms.

I have no idea how common this is but Fedora does enable this option. If you are interested in salvaging this, please speak up!

Thanks, Laura
