rtems/cpukit/score/cpu/avr/ChangeLog

2009-08-11	Josh Switnicki <josh.switnicki@utoronto.ca>

	* cpu.c, cpu_asm.S, rtems/score/cpu.h: Fix bug in
	_CPU_Context_Initialize.

2009-08-05	Josh Switnicki <josh.switnicki@utoronto.ca>

	* Makefile.am: added AVR specific Header files to score/cpu/avr/avr.
	These are from avr-libc 1.6 and assumed to exist by AVR applications.
	* preinstall.am: Regenerated.

2009-07-28	Joel Sherrill <joel.sherrill@oarcorp.com>

	* cpu.c, cpu_asm.S, rtems/score/cpu.h: Context switch now works well
	enough to run ticker to completion with the simulator clock idle
	task. But if you comment out the printk's in _CPU_Context_Initialize,
	it hangs. This remains to be investigated.

2009-07-23	Joel Sherrill <joel.sherrill@oarcorp.com>

	* cpu.c, cpu_asm.S: Unsuccessful attempt to fix.

2009-07-17	Josh Switnicki	<josh.switnicki@utoronto.ca>
	
	*cpu_asm.S: implemented _CPU_Context_Restore by adding tags to
	restore section of context switch.
	Fixed bug in _CPU_Context_Switch. The wrong registers were being
	used for pointer to running task Context_Control struct.

2009-07-09 	Josh Switnicki <josh.switnicki@utoronto.ca>

	* cpu_asm.S: Fixed bug in _CPU_Context_Switch. The wrong registers
	were being used for pointer to running task Context_Control
	struct.

2009-07-03  	Josh Switnicki <josh.switnicki@utoronto.ca>

	* cpu.c: Implemented _CPU_Context_Initialize as a C function instead
	of a macro.  It works with limited functionality.  Implemented
	_CPU_Thread_Idle_body to use sleep instruction.
	* Makefile.am: Changed cpu_asm.c -> cpu_asm.S
	* cpu_asm.S: renamed from cpu_asm.c and implemented functions is asm
	* rtems/asm.h: Appended "macros.inc" to the end of "asm.h" 
	* rtems/score/cpu.h:
	  + Included "avr/io.h".
	  + Added use 16 bit object definition. 
	  + Modified Context_Control struct to relect the registers
	    that need to be saved.
	  + Implemented _CPU_ISR_Disable, _CPU_ISR_Enable, and _CPU_ISR_Flash.
	    Added function definitions for _CPU_Context_Initialize and
	    _CPU_Push.

	consistently return void * and take a uintptr_t argument.

2009-02-11	Joel Sherrill <joel.sherrill@oarcorp.com>

	* cpu.c, rtems/score/cpu.h: Eliminate _CPU_Thread_dispatch_pointer and
	passing address of _Thread_Dispatch to _CPU_Initialize. Clean up
	comments.

2008-12-11	Joel Sherrill <joel.sherrill@oarcorp.com>

	* cpu.c, cpu_asm.c: Remove warnings -- even if code is just temporary.

2008-11-26	Joel Sherrill <joel.sherrill@oarcorp.com>

	* cpu.c, cpu_asm.c: Add debug printk() calls until the BSP/port can
	initialize and shutdown completely cleanly. When this works,
	implement context switch. Testing on avrtest and simulavr.

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

	* rtems/score/types.h: Do not define boolean, single_precision,

2008-06-05	Joel Sherrill <joel.sherrill@OARcorp.com>

	* rtems/score/cpu.h: Add CPU_SIMPLE_VECTORED_INTERRUPTS porting
	parameter to indicate that the port uses the Simple Vectored
	Interrupt model or the Programmable Interrupt Controller Model. The
	PIC model is implemented primarily in the BSP and it is responsible
	for all memory allocation.

2007-12-17	Joel Sherrill <joel.sherrill@oarcorp.com>

	* rtems/score/cpu.h: Add _CPU_Context_Get_SP() for stack check utility.
