a pre-release of merging loongson patchs to linux-2.6.29.1

[Wu Zhangjin <wuzhangjin@gmail.com>]

hi, all

these days, I am working on merging loongson patchs to linux-2.6.29.1, 
the fuloong(2f) & yeeloong source code have been completely merged to an
2f directory, most of the 2e & 2f source code have been merged except
the irq.c & reset.c, fixup-loongson2e.c & fixup-loongson2f.c.

the current directory architecture is as following:

$ tree arch/mips/loongson/
arch/mips/loongson/
|-- 2e
|   |-- Makefile
|   |-- irq.c
|   `-- reset.c
|-- 2f
|   |-- 8250.c
|   |-- Makefile
|   |-- clock.c
|   |-- cs5536.h
|   |-- cs5536_pci.h
|   |-- cs5536_vsm.c
|   |-- irq.c
|   |-- mfgpt.c
|   |-- mipsdha.c
|   |-- pcireg.h
|   `-- reset.c
|-- Kconfig
`-- common
    |-- Makefile
    |-- bonito-irq.c
    |-- dbg_io.c
    |-- mem.c
    |-- pci.c
    |-- prom.c
    `-- setup.c

$ tree arch/mips/include/asm/mach-loongson/
arch/mips/include/asm/mach-loongson/
|-- cpu-feature-overrides.h
|-- dma-coherence.h
|-- mc146818rtc.h
|-- mem.h
|-- pci.h
|-- prom.h
`-- war.h

$ ls arch/mips/pci/*loongson*
arch/mips/pci/fixup-loongson2e.c  arch/mips/pci/fixup-loongson2f.c

a current version is released to git://dev.lemote.com/rt4ls.git, 
(for avoid creating another git repository for it, i just use my
RT_PREEMPT git tree instead, so, it may be very big :-( )

$ git clone git://dev.lemote.com/rt4ls.git
$ git checkout linux-2.6.29-stable-loongson --track
origin/linux-2.6.29-stable-loongson

TODO:

   * clean up some of the commits carefully, especially the following
files:
   arch/mips/pci/fixup-loongson2*
   arch/mips/loongson/2f/cs5536* 
   irq.c, reset.c

   * try to merge the left files if possible.
   * update it to the latest mainline kernel and push it in.

best regards,
Wu Zhangjin
