commit 750bb80f2854d6af5273e55ea179a4c60b2d9efc
Author: Mike Kasick <mike@kasick.org>
Date:   Sun Jun 2 23:11:24 2013 -0400

    Clear download mode flag on kexec hardboot.

commit 138ba851ee949af291eae914f410aea2d85ed9f5
Author: Mike Kasick <mike@kasick.org>
Date:   Sun May 12 22:39:26 2013 -0400

    Support hard booting to a kexec kernel.

    See KEXEC_HARDBOOT config option help for details.

commit 3ab41019a7af08395c233bebb605c2f1ea49c8e0
Author: Mike Kasick <mike@kasick.org>
Date:   Sat Jul 7 23:10:24 2012 -0400

    Support copying of kernel tagged list (atags) in the decompressor.

    This is needed to hardboot kexec a kernel with a new tags list (including a
    new kernel command line), since the new atags would otherwise be lost with
    the limited kernel memory mapping.  Without this patch, a hardboot-kexec'd
    kernel uses the atags provided by the bootloader.

commit 446c3d7a6631877f7dc9142359cf0eae300e9a08
Author: Mike Kasick <mike@kasick.org>
Date:   Sat Jul 7 23:09:39 2012 -0400

    Enable caching and buffering for all of physical RAM in the decompressor.

    Old method is to enable caching and buffering only for the 256 MB at the
    start of the decompressor image.  This makes a hardboot-kexec'd kernel very
    slow to decompress since the decompressor is located far above the kernel
    destination.  This patch reduces boot time from 35 to 8 seconds on epicmtd.

commit d3646be88f5b1f9a8ae714c922ec50c681b7157f
Author: Mike Kasick <mike@kasick.org>
Date:   Sat Jul 7 19:00:47 2012 -0400

    Enable and fix kexec syscall support.

    Use mem_text_write_kernel_word when assigning reboot_code_buffer parameters
    to avoid protection faults (writes to read-only kernel memory) when
    CONFIG_STRICT_MEMORY_RWX is enabled.
