* rtems/score/cpu.h: In order to handle a issue in the
compilation of printk all tasks should be defined as
floating point for the MIPS processor.

PR 1635/cpukit
* rtems/score/cpu.h, rtems/score/types.h: Refactoring of priority
handling, to isolate the bitmap implementation of priorities in the
supercore so that priority management is a little more modular. This
change is in anticipation of scheduler implementations that can
select how they manage tracking priority levels / finding the highest
priority ready task. Note that most of the changes here are simple
renaming, to clarify the use of the bitmap-based priority management.
2010-07-16 Sebastian Huber <sebastian.huber@embedded-brains.de>
* rtems/score/cpu.h: Include <rtems/score/types.h> first.
* rtems/score/types.h: Use <rtems/score/basedefs.h> header file.
2010-07-01 Joel Sherrill <joel.sherrill@oarcorp.com>
* rtems/asm.h, rtems/score/cpu.h: cpu.h defines were not available to
assembly programs. This resulted in percpu.h (when included from
assembly) not being able to detect that the MIPS does not have a
dedicated software managed interrupt stack.
2010-06-28 Joel Sherrill <joel.sherrill@oarcorp.com>
PR 1573/cpukit

contains the information required by RTEMS for each CPU core. This
encapsulates information such as thread executing, heir, idle and
dispatch needed.

PR 1385/cpukit
* cpu_asm.S: When the type rtems_boolean was switched to the C99 bool,
the size changed from 4 bytes to 1 byte. The interrupt dispatching
code accesses two boolean variables for scheduling purposes and the
assembly implementations of this code did not get updated.

* 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.
2008-06-04 Joel Sherrill <joel.sherrill@OARcorp.com>
* rtems/score/cpu.h: Use a constant for CPU_STACK_MINIMUM_SIZE so it
can be used in cpp expressions. Using sizeof() requires actually
compiling the file.

predriver_hook, postdriver_hook, idle_task, do_zero_of_workspace,
extra_mpci_receive_server_stack, stack_allocate_hook, and
stack_free_hook. As a side-effect of this effort some multiprocessing

* rtems/score/Makefile.am: Reflect renaming mips64orion.h.
* asm.h: Include <mips.h> not <mips64orion.h>. Now includes the
few defines that were in <cpu_asm.h>.
* cpu.c (_CPU_ISR_Get_level): Added MIPS ISA I version of this routine.
MIPS ISA 3 is still in assembly for now.
(_CPU_Thread_Idle_body): Rewrote in C.
* cpu_asm.S: Rewrote file header.
(FRAME,ENDFRAME) now in asm.h.
(_CPU_ISR_Get_level): Removed ISA I version and rewrote in C.
(_CPU_ISR_Set_level): Removed ISA I version and rewrote in C.
(_CPU_Context_switch): MIPS ISA I now manages preserves SR_IEC and
leaves other bits in SR alone on task switch.
(mips_enable_interrupts,mips_disable_interrupts,
mips_enable_global_interrupts,mips_disable_global_interrupts,
disable_int, enable_int): Removed.
(mips_get_sr): Rewritten as C macro.
(_CPU_Thread_Idle_body): Rewritten in C.
(init_exc_vecs): Rewritten in C as mips_install_isr_entries() and
placed in libcpu.
(exc_tlb_code, exc_xtlb_code, exc_cache_code, exc_norm_code): Moved
to libcpu/mips/shared/interrupts.
(general): Cleaned up comment blocks and #if 0 areas.
* idtcpu.h: Made ifdef report an error.
* iregdef.h: Removed warning.
* rtems/score/cpu.h (CPU_INTERRUPT_NUMBER_OF_VECTORS): Now a variable
number defined by libcpu.
(_CPU_ISR_Disable, _CPU_ISR_Enable): Rewritten to use new routines
to access SR.
(_CPU_ISR_Set_level): Rewritten as macro for ISA I.
(_CPU_Context_Initialize): Honor ISR level in task initialization.
(_CPU_Fatal_halt): Use new _CPU_ISR_Disable() macro.

* rtems/score/cpu.h: When mips ISA level is 1, registers in the
context should be 32 not 64 bits.
2000-11-30 Joel Sherrill <joel@OARcorp.com>
* cpu_asm.S: Changed "_CPU_Ccontext_switch_restore: typo to
correct name of _CPU_Context_switch_restore. Added dummy
version of exc_utlb_code() so applications would link.
2000-11-09 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
* Makefile.am: Use ... instead of RTEMS_TOPdir in ACLOCAL_AMFLAGS.
2000-11-02 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
* Makefile.am: Switch to ACLOCAL_AMFLAGS = -I $(RTEMS_TOPdir)/aclocal.
2000-10-25 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
* Makefile.am: ACLOCAL_AMFLAGS= -I $(RTEMS_TOPdir)/macros.
Switch to GNU canonicalization.

* This is a major reworking of the mips64orion port to use
gcc predefines as much as possible and a big push to multilib
the mips port. The mips64orion port was copied/renamed to mips
to be more like other GNU tools. Alan did most of the technical
work of determining how to map old macro names used by the mips64orion
port to standard compiler macro definitions. Joel did the merge
with CVS magic to keep individual file history and did the BSP
modifications. Details follow:
* Makefile.am: idtmon.h in mips64orion port not present.
* asm.h: MIPS64ORION replaced with MIPS. Frame setup macros added.
* cpu.c: Comments added.
* cpu_asm.S: Conditionals changed. MIPS ISA level 1 support added.
First attempt at exception/interrupt processing for ISA level 1
and minus any use of IDT/MON added.
* idtcpu.h: Conditionals changed to use gcc predefines.
* iregdef.h: Ditto.
* cpu_asm.h: No real change. Merger required commit.
* rtems/Makefile.am: Ditto.
* rtems/score/Makefile.am: Ditto.
* rtems/score/cpu.h: Change MIPS64ORION to MIPS.
* rtems/score/mips64orion.h: Change MIPS64ORION to MIPS. Convert
from using RTEMS_CPU_MODEL to gcc predefines to figre things out.
2000-09-04 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
* Makefile.am: Include compile.am.
2000-08-10 Joel Sherrill <joel@OARcorp.com>
* ChangeLog: New file.
