-Subject: MIPS: Kexec: Enhance the support
-
-Changes:
-  o Print more information in machine_kexec() for debugging
-    E.g. with this information, the kexec_start_address has been found
-    it was wrong with 64bit kernel / o32 kexec-tools. Which must be
-    fixed later.
-  o Link relocate_kernel.S to a section for future extension
-    This allows more functions can be added for the kexec relocation
-    part even written in C. to add code into that section, you just need
-    to mark your function or data with __kexec or
-    __attribute__((__section__(".__kexec.relocate")))
-
-TODO:
-
-1. Make 64bit kernel / o32|n32|64 kexec-tools works
-
-Fix the user-space kexec-tools, seems the tool only work for 32bit
-machine. So, we need to add 64bit support for it. The address of the
-entry point(kexec_start_address) is wrong and make the "kexec -e" fail.
-the real entry point must be read from the new kernel image by the
-user-space kexec-tools, otherwise, it will not work.  The above 64bit
-support tested is 64bit kernel with o32 user-space kexec-tools. The root
-cause may be the different definition of virt_to_phys() and
-phys_to_virt() in the kexec-tools and kernel space for 64bit system /
-o32 kernel.

-
-2. Pass the arguments from kexec-tools to the new kernel image
-
-Please refer to: "MIPS: Loongson: Kexec: Pass parameters to new kernel"
