This patch declare the rtc device present on systems with clock compatible with the mc146818 and handled by rtc-cmos. Introduce a new Kconfig entry because there are some systems without rtc_cmos compatible clock.

This patchs uses a loongson_uart_base variable instead of the uart_base[] array and adds a new kernel option to avoid to compile uart_base.c all the time, which will save a little bit of memory for us.

Loongson 2F supports CPU clock scaling. When put it into wait mode by setting the frequency as ZERO it will stay in this mode until an external interrupt wakes the CPU again. To enable clock scaling support, an external timer of a known stable rate is required.

CPUFreq support for Loongson 2F requires an external timer. Because the frequency of the MIPS Timer is related to the CPU frequency which itself is variable another timer of constant frequency is required. Export the mfgpt0 counter disable / enable operations for the coming suspend support to suspend / resume the timer.

This patch add basic suspend support for loongson2f family machines, loongson2f have a specific feature: when we set it's frequency to ZERO, it will go into a wait mode, and then can be waked up by the external interrupt. so, if we setup suitable interrupts before putting it into wait mode, we will be able wake it up whenever we want via sending the relative interrupts to it. These interrupts are board-specific, Yeeloong2F use the keyboard interrupt and SCI interrupt, but LingLoong and Fuloong2F use the interrupts connected to the processors directly. and BTW: some old LingLoong and FuLoong2F have no such interrupts connected, so, there is no way to wake them up from suspend mode. and therefore, please do not enable the kernel support for them. The board-specific support will be added in the coming patches.

Lemote Loongson 2F family machines use CS5536 as their south bridge and need these lowlevel interfaces to access the devices on CS5536. Virtualize the legacy devices on CS5536 as PCI devices. This way users can access the CS5536 PCI config space directly as a normal multi-function PCI 2.2 device.

Add a new kernel option for Lemote Loongson 2F family machines. Lemote loongson2f family machines utilize the 2f revision of loongson processor and the AMD CS5536 south bridge. Family members include Fuloong 2F mini PC, Yeeloong 2F notebook, LingLoong all-in-one PC and others.

Because only gcc >=4.4 have loongson-specific support, we need to choose the suitable -march argument for gcc <= 4.3 and gcc >= 4.4, and here, we use -march=loongson2e for loongson2e. Thanks goes to Arnaud Patard <apatard@mandriva.com> for suggestion of using cc-options(Documentation/kbuild/makefiles.txt). and thanks Zhang Le for introducing the new CPU_LOONGSON2E kernel option. NOTE: -mtune option is not need if -march and -mtune use the same value.

To share common loongson source code between all of the loongson-based machines. there is a need to split it out of the fuloong-2e/ directory. at the same time, other according tuning is needed. the machine-specific parts are defined as macros in relative header file, pci.h, mem.h, machine.h.
