* cpu.c, cpu_asm.S, score/cpu.h : add support for ARM<->THUMB veneer
thumb new dir to controll CPSR/SPRS in thumb mode
2007-05-09 Ray Xu <rayx.cn@gmail.com>
* cpu.c: move do_data_abort() to libbsp/arm/shared/abort/
implement a compact do_data_abort() in simple_abort.c
* cpu.c, cpu_asm.S, rtems/score/arm.h, rtems/score/cpu.h,
rtems/score/cpu_asm.h, rtems/score/types.h: ARM port works
well enough to run all sptests, tmtests, and ttcp.
In addition to general cleanup, there has been considerable
optimization to interrupt disable/enable, endian swapping,
and context switching.
* rtems/score/cpu_asm.h: Enhanced to include register offsets.
* Makefile.am: Install rtems/score/cpu_asm.h.
* cpu.c: Significantly enhanced including the implementation of
_CPU_ISR_Get_level.
* cpu_asm.S: Improved behavior of context switch and interrupt
dispatching.
* rtems/score/arm.h: Improved the CPU model name determination.
* rtems/score/cpu.h: Improved interrupt disable/enable functions.

basic BSP that is sufficient to link hello world.
