Subject: [PATCH 0/2] EFI earlyprintk support
Date: Fri, 11 Oct 2013 15:33:55 +0100 [thread overview]
Message-ID: <1381502037-22225-1-git-send-email-matt@console-pimps.org> (raw)
From: Matt Fleming <matt.fleming@intel.com>
These two patches cleanup the #include <linux/efi.h> duplication and add
support for earlyprintk=efi, which is the only way users can debug early
boot crashes without special hardware.
Matt Fleming (2):
x86/efi: Include linux/efi.h in asm/efi.h
x86/efi: Add EFI framebuffer earlyprintk support
