2010-04-08      Sebastian Huber <sebastian.huber@embedded-brains.de>

        * arm_exc_abort.S, arm_exc_handler_high.c, arm_exc_handler_low.S,
        arm_exc_interrupt.S, cpu.c, cpu_asm.S, rtems/asm.h, rtems/score/arm.h,
        rtems/score/cpu.h, rtems/score/cpu_asm.h, rtems/score/types.h:
        Documentation.

2010-04-07      Joel Sherrill <joel.sherrill@oarcorp.com>

        * arm_exc_abort.S: Fix warnings about TRUE/FALSE not defined.

2010-03-27      Joel Sherrill <joel.sherrill@oarcorp.com>

        * arm_exc_abort.S, arm_exc_handler_high.c, arm_exc_handler_low.S,
        arm_exc_interrupt.S, cpu.c, cpu_asm.S: Add include of config.h

2010-01-12      Sebastian Huber <sebastian.huber@embedded-brains.de>

        * arm_exc_abort.S: New file.
        * Makefile.am: Update for new file.
        * arm_exc_interrupt.S, cpu.c, rtems/asm.h, rtems/score/cpu.h: Changed
        macros which switch from and to THUMB mode.  Added a default prefetch
        and data abort handler which reports the complete processor context.
        Added PSR defines.

2009-12-15      Sebastian Huber <sebastian.huber@embedded-brains.de>

        * rtems/score/arm.h: Recognize ARMv5TEJ.
        * arm_exc_interrupt.S: The previous implementation was broken.  In
        case of a nested interrupt the link register of the INT mode was not
        properly restored.  This lead to a major rewrite.  Interrupt
        processing is now done in SVC mode.

2009-10-01      Joel Sherrill <joel.sherrill@oarcorp.com>

        * rtems/score/arm.h: Recognize ARMv7A.

2009-10-01      Joel Sherrill <joel.sherrill@oarcorp.com>

        * rtems/score/arm.h: Recognize ARMv6J as needed by arm1136 variants.

2009-09-15      Sebastian Huber <sebastian.huber@embedded-brains.de>

        * rtems/score/cpu.h: Fix for inline asm in _CPU_Fatal_halt().
        * rtems/asm.h: Added macro to define ARM functions.
        * cpu_asm.S, arm_exc_handler_low.S: Use macro from above.

2009-08-19      Joel Sherrill <joel.sherrill@OARcorp.com>

        * rtems/score/cpu.h: Mark _CPU_Context_restore() as noreturn so the
        compiler will not generate code thinking it returns.

2009-07-15      Sebastian Huber <sebastian.huber@embedded-brains.de>

        * arm_exc_handler_high.c, arm_exc_handler_low.S, arm_exc_interrupt.S:
        New files.
        * Makefile.am: Update.
        * rtems/score/cpu.h:  Removed all generic comments.  Changed inline
        assembler of interrupt support functions.  Removed operating system
        support for fast interrupts (FIQ).  Overall cleanup.
        * cpu.c: Changed type of arm_cpu_mode to uint32_t to match the type in
        _CPU_Context_Initialize().  Moved exception handler code into
        'arm_exc_handler_high.c'.  _CPU_ISR_install_vector() writes now only
        if necessary.
        * cpu_asm.S: Moved exception handler code into 'arm_exc_handler_low.S'.
        * rtems/score/types.h: Removed superfluous defines.

        passing address of _Thread_Dispatch to _CPU_Initialize. Clean up
        comments.

2008-09-11      Ralf Corsépius <ralf.corsepius@rtems.org>

        * rtems/score/types.h: Do not define boolean, single_precision,
        double_precision unless RTEMS_DEPRECATED_TYPES is given.

2008-09-08      Joel Sherrill <joel.sherrill@oarcorp.com>

        extra_mpci_receive_server_stack, stack_allocate_hook, and
        stack_free_hook. As a side-effect of this effort some multiprocessing
        code was made conditional and some style clean up occurred.

2007-11-27      Joel Sherrill <joel.sherrill@OARcorp.com>
