10        * rtems/score/cpu.h, rtems/score/types.h: Refactoring of priority
11        handling, to isolate the bitmap implementation of priorities in the
12        supercore so that priority management is a little more modular. This
13        change is in anticipation of scheduler implementations that can
14        select how they manage tracking priority levels / finding the highest
15        priority ready task. Note that most of the changes here are simple
16        renaming, to clarify the use of the bitmap-based priority management.

107        enough to run ticker to completion with the simulator clock idle
108        task. But if you comment out the printk's in _CPU_Context_Initialize,
109        it hangs. This remains to be investigated.

131        of a macro.  It works with limited functionality.  Implemented
132        _CPU_Thread_Idle_body to use sleep instruction.
133        * Makefile.am: Changed cpu_asm.c -> cpu_asm.S
134        * cpu_asm.S: renamed from cpu_asm.c and implemented functions is asm
135        * rtems/asm.h: Appended "macros.inc" to the end of "asm.h"

207        parameter to indicate that the port uses the Simple Vectored
208        Interrupt model or the Programmable Interrupt Controller Model. The
209        PIC model is implemented primarily in the BSP and it is responsible
210        for all memory allocation.
