LOONGSON_UART_BASE depends on EARLY_PRINTK || SERIAL_8250, but when neither of these Kconfig symbols is set, the kernel build has errors: ../arch/mips/loongson2ef/common/serial.c: In function 'serial_init': ../arch/mips/loongson2ef/common/serial.c:66:25: error: 'loongson_uart_base' undeclared (first use in this function) 66 | loongson_uart_base; ../arch/mips/loongson2ef/common/serial.c:66:25: note: each undeclared identifier is reported only once for each function it appears in ../arch/mips/loongson2ef/common/serial.c:68:41: error: '_loongson_uart_base' undeclared (first use in this function) 68 | (void __iomem *)_loongson_uart_base; Fix this by building serial.o only when one (or both) of these Kconfig symbols is enabled. Tested with: (a) EARLY_PRINTK=y, SERIAL_8250 not set; (b) EARLY_PRINTK=y, SERIAL_8250=y; (c) EARLY_PRINTK=y, SERIAL_8250=m. (d) EARLY_PRINTK not set, SERIAL_8250=y; (e) EARLY_PRINTK not set, SERIAL_8250=m; (f) EARLY_PRINTK not set, SERIAL_8250 not set.
