-   Removed the part from memtest86+ 'make' where it tried to connect

-   X60 now uses a single grub.cfg (for grub memdisk)
-   X60 now uses a single grub.elf (payload)
-   Added new native graphics code for X60 (replaces the old 'replay'
    code) from Vladimir Serbinenko: 5320/9 from review.coreboot.org
-   T60 is now supported, with native graphics. (5345/4 from
    review.coreboot.org, cherry-picked on top of 5320/9 checkout)

    Serbinenko) from review.coreboot.org (see 'getcb' script to know

        running (on X60/T60)
-   Added 'flash' script (make sure to run builddeps-flashrom first)
    which (while libreboot is already running) can use flashrom to flash
    a ROM
    -   eg: "sudo ./flash bin/x60/coreboot\_serial\_ukdvorak.rom"
        equivalent to "sudo ./flashrom/flashrom -p internal -w

    -   Created patched version of the relevant source files and added
        it into resources/cbfstool/patch

            version in resources/cbfstool/patch/rmodule.c
        -   see coreboot/src/include/rmodule-defs.h and the rule in
            'build' for including this in

        to the cbfstool\_standalone source in libreboot\_bin
    -   Added instructions to 'build' script for then re-compiling
        cbfstool\_standalone in libreboot\_bin after applying the patch
    -   Added a 'builddeps-cbfstool' script (in src, but only used in
        bin and put in bin by 'build') that compiles
        cbfstool\_standalone in libreboot\_bin (make), moves the
        cbfstool and rmodtool binaries into libreboot\_bin/ and then
        does 'make clean' in libreboot\_bin/cbfstool\_standalone
    -   Updated the 'build' script to put 'builddeps-cbfstool' in
        libreboot\_bin
    -   Updated the 'build' script in the cbfstool (standalone) part

    the LCD panel on a T60 14.1' XGA or 15.1' XGA)
    -   it's FRU P/N 41W1478 (on T60 14.1") so this was added to the
        docs.
    -   it's P/N 42T0078 FRU 42T0079 or P/N 41W1338 (on T60 15.1") so
        this was added to the docs.
-   Documentation: added information about names of LCD panels for T60
    to the relevant parts of the documentation.

    differences between T60 with Intel GPU and T60 with ATI GPU.

    (they don't really belong there)
-   Added libfuse-dev and liblzma-dev to the list of GRUB dependencies
    in 'builddeb' script.
