Subject: [PATCH 5.4 343/411] m68knommu: fix undefined reference to `_init_sp

From: Greg Ungerer <gerg@...ux-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.
