commit 5514619a36b91829805022103f8f7c358c939c28
Author: Marc Jones <marc.jones at se-eng.com>
Date:   Thu May 10 11:02:32 2012 -0600

    Add legacy free setting and override to fadt.c
    
    The FADT iapc_boot_arch indicates the available information
    for accessing legacy devices. By default, the setting supports
    legacy. LEGACY_FREE and/or the iapc_boot_arch field may be
    customized.
