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

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
