[git pull request] SFI for Linux

[Len Brown <lenb@kernel.org>]

Hi Linus,

please pull from: 

git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-sfi-2.6.git sfi-release

This tree supports the Simple Firmware Interface for Linux
http://simplefirmware.org/ which is required in order to boot Linux
on Intel's upcoming Moorestown platform.

The x86 maintainers have acked the bits that touch x86, though
I didn't re-base the patches to note that because the commits
are shared by multiple trees.

Also, if you pull this tree before pulling the ACPI tree,
you'll pull along a few preceeding ACPI patches that were
necessary to add SFI support.

thanks!

    SFI: Hook PCI MMCONFIG
    
    First check ACPI, and if that fails, ask SFI to find the MCFG.

    x86: add arch-specific SFI support
    
    arch/x86/kernel/sfi.c serves the dual-purpose of supporting the
    SFI core with arch specific code, as well as a home for the
    arch-specific code that uses SFI.
    
    analogous to ACPI, drivers/sfi/Kconfig is pulled in by arch/x86/Kconfig

    SFI: add capability to parse ACPI tables
    
    Extend SFI to access standard ACPI tables.
    (eg. the PCI MCFG) using sfi_acpi_table_parse().
    
    Note that this is _not_ a hybrid ACPI + SFI mode.
    The platform boots in either ACPI mode or SFI mode.
    
    SFI runs only with acpi_disabled=1, which can be set
    at build-time via CONFIG_ACPI=n, or at boot time by
    the failure to find ACPI platform support.
    
    So this extension simply allows SFI-platforms to
    re-use existing standard table formats that happen to
    be defined to live in ACPI envelopes.

    SFI: add platform-independent core support
    
    drivers/sfi/sfi_core.c contains the generic SFI implementation.
    It has a private header, sfi_core.h, for its own use and the
    private use of future files in drivers/sfi/

    SFI: create linux/sfi.h
    
    include/linux/include/sfi.h defines everything that customers
    of SFI need to know in order to use the SFI suport in the kernel.
    
    The primary API is sfi_table_parse(), where a driver or another part
    of the kernel can supply a handler to parse the named table.
    
    sfi.h also includes the currently defined table signatures and table
    formats.

    SFI: Simple Firmware Interface - MAINTAINERS, Kconfig
    
    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 both in emulation
    and on Moorestown hardware.
    
    See http://simplefirmware.org for more information on SFI.
