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.

early_printk.c is doing the same with early_printk_8250.
Remove duplicated code.

MIPS: Loongson{2ef, 32, 64} convert to generic fw cmdline2019-11-11T18:44:56ZJiaxun Yangjiaxun.yang@flygoat.com2019-11-07T04:01:15Zurn:sha1:75cac781dca43e735fbb4166d994263a14f0823e
All of Loongson firmwares are passing boot cmdline/env
in the manner of YAMON/PMON. Thus we can remove duplicated
cmdline initialize code and convert to generic fw method.

MIPS: Fork loongson2ef from loongson642019-11-01T21:30:52ZJiaxun Yangjiaxun.yang@flygoat.com2019-10-20T14:43:14Zurn:sha1:71e2f4dd5a65bd8dbca0b77661e75eea471168f8
As later model of GSx64 family processors including 2-series-soc have
similar design with initial loongson3a while loongson2e/f seems less
identical, we separate loongson2e/f support code out of mach-loongson64
to make our life easier.
This patch contains mostly file moving works.
