* asm.h, cpu.c, rtems.c, rtems/score/cpu.h, rtems/score/sh.h, rtems/score/sh_io.h, rtems/score/shtypes.h: Consistency changes and made sure there were no includes from the libcpu tree.

* cpu.c, rtems/score/cpu.h, rtems/score/sh.h: Modified to support SH4. Reviewed by Ralf Corsepius <corsepiu@faw.uni-ulm.de> who did the original SH port.
2001-10-122001-10-12 Joel Sherrill <joel@OARcorp.com>Joel Sherrill2-2/+8
* cpu_asm.S: _CPU_Context_save_fp in was incorrectly in conditional compilation block with (CPU_HARDWARE_FP == FALSE). Reported by Wayne Bullaughey <wayne@wmi.com>.

* cpu_asm.S: Small patch to fix a bug in the rtems sparc port. The bug has been there all the time, but only hits the leon bsp since the leon cpu has a 5-stage pipeline (erc32 has 4 stages).

* rtems/score/Makefile.am: Use 'PREINSTALL_FILES ='. * Makefile.am: Use 'PREINSTALL_FILES ='.

* cpu.c (_CPU_ISR_install_vector): Corrected interrupt range checking which was SH1 specific. It didn't work for SH2 (has more interrupt sources).
2001-08-092001-08-09 Chris Johns <ccj@acm.org>Joel Sherrill2-63/+48
* cpu_asm.S: This patch was co-developed with Eric Norum <eric.norum@usask.ca>. It closes a one instruction window on some m68k CPU cores. It fixes symptoms seen as: 1) No more `interrupt handler invoked twice for a single interrupt'. 2) No more `lockup when mc68360 CPM and PIT interrupts are at different levels'. It does insert a little more overhead on machines without hardware interrupt stacks but correctness has a price.

* cpu.c: Fixed typo.
2001-05-242000-05-24 Joel Sherrill <joel@OARcorp.com>Joel Sherrill1-7/+38
* rtems/score/mips.h: Added constants for MIPS exception numbers. All exceptions should be given low numbers and thus can be installed and processed in a uniform manner. Variances between various MIPS ISA levels were not accounted for.

* Assisted in design and debug by Joel Sherrill <joel@OARcorp.com>. * cpu_asm.S: Now works on Mongoose-V. Missed in previous patch.
2001-05-222001-05-22 Greg Menke <gregory.menke@gsfc.nasa.gov>Joel Sherrill3-21/+86
* rtems/score/cpu.h: Add the interrupt stack structure and enhance the context initialization to account for floating point tasks. * rtems/score/mips.h: Added the routines mips_set_cause(), mips_get_fcr31(), and mips_set_fcr31(). * Assisted in design and debug by Joel Sherrill <joel@OARcorp.com>.

2001-04-202001-04-20 Joel Sherrill <joel@OARcorp.com>Joel Sherrill2-0/+15
* cpu_asm.S: Added code to save and restore SR and EPC to properly support nested interrupts. Note that the ISR (not RTEMS) enables interrupts allowing the nesting to occur.
2001-04-112001-04-11 Joel Sherrill <joel@OARcorp.com>Joel Sherrill2-2/+4
* cpu.c: Removed duplicate declaration for _ISR_Vector_table.

* cpu.c, cpu_asm.S, iregdef.h, rtems/score/cpu.h, rtems/score/mips.h: Merged MIPS1 and MIPS3 code reducing the number of lines of assembly. Also reimplemented some assembly routines in C further reducing the amount of assembly and increasing maintainability.
2001-02-052001-02-04 Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill49-113/+191
* Makefile.am, rtems/score/Makefile.am: Apply include_*HEADERS instead of H_FILES.

* cpu.c, rtems/score/cpu.h: Bug report from Peter Mueller <peter.o.mueller@gmx.de> because of not correcting for the ISR vector table now being allocated from the workspace.
2001-01-122001-01-12 Joel Sherrill <joel@OARcorp.com>Joel Sherrill2-2/+7
* rtems/score/mips.h (mips_get_sr, mips_set_sr): Corrected register constraints from "general" to "register".
2001-01-092001-01-09 Joel Sherrill <joel@OARcorp.com>Joel Sherrill4-6/+27
* cpu_asm.S: Use SR_INTERRUPT_ENABLE_BITS instead of SR_XXX constants to make it easier to conditionalize the code for various ISA levels.
2001-01-082001-01-08 Joel Sherrill <joel@OARcorp.com>Joel Sherrill4-3/+16
* idtcpu.h: Commented out definition of "wait". It was stupid to use such a common word as a macro. * rtems/score/cpu.h (_CPU_ISR_Disable): Fixed for mips ISA 3. * rtems/score/mips.h: Added include of <idtcpu.h>. * rtems/score/mips.h (mips_enable_in_interrupt_mask): Corrected.

* cpu_asm.S (_ISR_Handler): Return to the address in the EPC register. Previous code resulting in the interrupted immediately returning to the caller of the routine it was inside.
2000-12-192000-12-19 Joel Sherrill <joel@OARcorp.com>Joel Sherrill2-11/+5
* cpu.c (_CPU_Initialize): Do not initialize _ISR_Vector_table() here because it has not been allocated yet.
2000-12-192000-12-19 Joel Sherrill <joel@OARcorp.com>Joel Sherrill2-1/+8
* cpu.c: Do not read or write raw interrupt vector table if we are on a CPU that does not have a %vbr register and the BSP is configured as having the table in ROM.
2000-12-132000-12-13 Joel Sherrill <joel@OARcorp.com>Joel Sherrill4-82/+16
* cpu.c: Removed duplicate declaration for _ISR_Vector_table. * cpu_asm.S: Removed assembly language to vector ISR handler on MIPS ISA I. Now call mips_vector_isr_handlers() in libcpu or BSP. * rtems/score/cpu.h (CPU_INTERRUPT_NUMBER_OF_VECTORS): No longer a constant -- get the real value from libcpu.

* 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.
