I took a look on it.

I can build 'qemu' target with default config, but I can't see
any output in emulator.

I can't even build 'malta' target with default config.

Is it runnable at all?

I think, that Shinya's concepts can be used in the future, but they
are very complex for initial mips support.

IMHO, the Shinya's code is redundant (> 200K ) --- initial support
must be as small as possible.

The file Kconfig is overcomplicated. Many variables are really unused:
 DMA_NONCOHERENT,
 SWAP_IO_SPACE
 HW_HAS_PCI
 SYS_SUPPORTS_{32,64}BIT_KERNEL
 SYS_SUPPORTS_ARBIT_HZ
  and others

In other hand the options ARCH_TEXT_BASE and CPU_BIG_ENDIAN are useful
just now, but I have missed them.

But now I see, that I can make my mips support better --- split big
patch and make some parts of code configurable.
