[PATCHv2 00/11] unicore32 core architecture

[Guan Xuetao]

From: Guan Xuetao <gxt@xxxxxxxxxxxxxxx>

The whole subsystem code could be fetched from:
  git://git.kernel.org/pub/scm/linux/kernel/git/epip/linux-2.6-unicore32.git
  with branch name: unicore32.
And it is divided into  three patch sets: core architecture files,
  additional architecture files, and machine related files.

This patch set adds the core architecture support for UniCore32 ISA. 

Patch 1 implements build infrastructure.

Patch 2 includes some generic stuff including elf and ksyms.
Because all one-line asm-generic headers are auto-generated by ASM_GENERIC_HEADERS
in arch/unicore32/Makefile, so the rest seems very little.
ELF handling functions and module handling functions are also here.

Patch 3 includes processor and system headers. System call interface is here.
We used the syscall interface the same as asm-generic version.

Patch 4 implements low level entry and setup codes.

Patch 5 implements process/thread related codes. Backtrace and stacktrace are here.

Patch 6 includes generic codes of memory management.

Patch 7 implements fault handling of memory management.

Patch 8 implements consistent device DMA handling of memory management.
  DMA device operations are also here.

Patch 9 implements timer and time. RTC and PWM device drivers are also here.

Patch 10 implements interrupts and gpio. UniCore32 has 9 gpio interrupt sources.
  And gpio device operations are also here.

Patch 11 implements signals.
