It does not help the hibernation issue, but helps to clear the memory
layout to the users(cat /proc/iomem), is this a need?
Seems some of the other architectures, including some MIPS variants have
registed the reserved space, so, could you please apply it?

The uart_base variable here is not a physical address, so, we replace it
by unsigned char *.

There is an existing serial port debug function: prom_putchar(), but it
can only print one char, herein add a new prom_printf(), which works
like printk, but print to serial port, which is very important to kernel
debugging.

Does this mean early_printk doesn't work for you? We rather get that to
work for you than introducing something equivalent.

This patch add serial port support for all of the existing loongson
family machines. most of the board specific part are put in serial.c,
and the base address of the serial ports are defined as macros in
machine.h for sharing it between serial.c and early_printk.c

There is a built-in northbridge in loongson2e/2f, which is bonito64
compatiable, but it differs from bonito64. to avoid influencing the
original bonito64 support and make the loongson support more
maintainable, it's better to remove reference from bonito64.
And this patch is a very important preparation for the coming loongson2f
family machines' support, all the coming patches depend on it.
