Subject: [PATCH] efifb: Update documentation to include generic EFI 1.1 and UEFI 2.0 platforms
Date: Thu, 08 Dec 2011 11:40:24 -0800 [thread overview]
Message-ID: <4EE112A8.5030006@linux.intel.com> (raw)
According to the Kconfig help, efifb supports EFI 1.1 and UEFI 2.0 platforms
in addition to the Intel based Macs. I have Atom development platforms that
require CONFIG_FB_EFI for kernel output to the display console. I have left
the Mac kernel parameters alone as I do not have hardware to test it.
