    powerpc/boot: Add support for 64bit little endian wrapper · 147c0516
    Cédric Le Goater authored
    The code is only slightly modified : entry points now use the
    FIXUP_ENDIAN trampoline to switch endian order. The 32bit wrapper
    is kept for big endian kernels and 64bit is enforced for little
    endian kernels with a PPC64_BOOT_WRAPPER config option.
    
    The linker script is generated using the kernel preprocessor flags
    to make use of the CONFIG_* definitions and the wrapper script is
    modified to take into account the new elf64ppc format.
    
    Finally, the zImage file is compiled as a position independent
    executable (-pie) which makes it loadable at any address by the
    firmware.
