Subject: [PATCH 1/8] SFI: Simple Firmware Interface - new Linux sub-system
From: Len Brown <len.brown@...el.com>
CONFIG_SFI=y enables the kernel to boot and run optimally
on platforms that support the Simple Firmware Interface.
Thanks to Jacob Pan for prototyping the initial Linux SFI support,
and to Feng Tang for Linux bring-up and debug in emulation
and on hardware.
See http://simplefirmware.org for more information on SFI.
