[RFC PATCH 00/23] grub 64bit little-endian on power

[Ram Pai <linuxram@us.ibm.com>]

The following patches enable grub to support
64bit Little Endian Power architecture.

Anton Blanchard (12):
  Add IEEE1275_ADDR helper
  Fix some more warnings when casting.
  Add powerpc64 types
  Fix warnings when building powerpc linux loader 64bit
  Fix powerpc setjmp/longjmp 64bit issues
  Add powerpc64 ieee1275 trampoline
  Add 64bit support to powerpc startup code
  Add grub_dl_find_section_addr
  Add ppc64 relocations
  ppc64 doesn't need libgcc routines
  Use FUNC_START/FUNC_END for powerpc function definitions
  powerpc64 is not necessarily BigEndian anymore! :)

Ram Pai (11):
  Add a new architecture to the build process
  Build grub as O1 until we add savegpr and restgpr routines
  powerpc64 LE's linker knows how to handle the undefined symbol .TOC.  
      in grub modules. So just ignore that symbol during build.
  grub-install can now recognize and install a LE grub boot loader
  set the ABI version to 0x02 in the e_flag of the PPC64LE ELF image.
  GRUB_ELF_R_PPC_* processing is applicable only for 32 bit bootloader.
  .TOC. symbol is special in ppc64le . It maps to the address of the
    .toc     section.
  the .toc section in powerpc64le modules are sometimes not aligned on a
    four     byte boundary. This fails the module linker especially when
    processing     R_PPC64_TOC16_LO_DS, since the addresses are expected
    to be aligned on 4byte     boundary.
  all parameter to firmware calls should to be BigEndian and the results
        should be CPU endian.
  grub segfaults if initrd is specified before specifying the kernel.   
     The problem is the initrd module sees that kernel is not specified 
       and takes the fail path. In the fail path it checks if anything
    has     be malloc'ed. Unfortunately the variable that it looks to
    check for     is a uninitialized stack variable. The stack variable
    can incorrectly     indicate something is malloced, which leads the
    module to free some     unallocated memory. This patch fixes the
    problem by initializing the     stack variable.
  Power7 cannot handle VSX instructions correctly. It segfaults.    
    This patch is applicable only for power7 systems.
