    Subject[PATCH 4.9 130/167] m68knommu: fix undefined reference to `_init_sp
    Date
    From: Greg Ungerer <gerg@linux-m68k.org>

    [ Upstream commit a71b9e66fee47c59b3ec34e652b5c23bc6550794 ]

    When configuring a nommu classic m68k system enabling the uboot parameter
    passing support (CONFIG_UBOOT) will produce the following compile error:

    m68k-linux-ld: arch/m68k/kernel/uboot.o: in function `process_uboot_commandline':
    uboot.c:(.init.text+0x32): undefined reference to `_init_sp'

    The logic to support this option is only used on ColdFire based platforms
    (in its head.S startup code). So make the selection of this option
    depend on building for a ColdFire based platform.

    If you say Y here kernel will try to collect command
    line parameters from the initial u-boot stack.
