If NIOS2_CMDLINE_IGNORE_DTB is selected but CMDLINE_BOOL isn't and thus CONFIG_CMDLINE is not defined, the build fails with the following error: arch/nios2/kernel/setup.c: In function 'nios2_boot_init': arch/nios2/kernel/setup.c:131:30: error: 'CONFIG_CMDLINE' undeclared (first use in this function) strncpy(boot_command_line, CONFIG_CMDLINE, COMMAND_LINE_SIZE); This can be reproduced using randconfig with KCONFIG_SEED=0xE5B8749E, i.e. 'make KCONFIG_SEED=0xE5B8749E ARCH=nios2 randconfig'. Fix this by letting NIOS2_CMDLINE_IGNORE_DTB depend on CMDLINE_BOOL, so we actually have a default kernel command string to fall back to. Signed-off-by:
