From: Greg Ungerer <gerg@linux-m68k.org> stable inclusion from stable-v5.10.122 commit 2c08cae19d5d0d15d6daf3fb781d0d1d980b5a93 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I5W6OE Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ 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.
