[PATCH 0/9] x86 EFI boot stub

From: Matt Fleming
Date: Thu Aug 11 2011 - 06:59:54 EST

From: Matt Fleming <matt.fleming@xxxxxxxxx>

This series adds support for an EFI boot stub, similar to the existing
BIOS boot stub. The result is that you can boot a bzImage on an EFI
machine without the use of a boot loader by making the bzImage appear
to the EFI firmware to be an EFI application. Also, a single bzImage
can be booted on either a BIOS or EFI machine.

Using the EFI boot stub has the advantage that the kernel is
responsible for configuring the machine to the point where we can
fully boot the kernel, so we are no longer at the mercy of the boot

This series is also available in the 'x86/efi-stub' branch at,
