326 6808 d 0 h palkovsky /SPARTAN/trunk/ Cleanup of makefiles to have common options in one main makefile.

Add simple build process for different simulators for MIPS.
Added FPU context & lazy FPU context switching to MIPS.
Cleanup of MIPS linker script.
Moved MIPS kernel above 1MB. Not tested on real machine yet, but it might help.

There is something broken with gcc inlined memcpy (either simulator or gcc), it is disabled on BigEndian mips now.		  
324 6808 d 11 h palkovsky /SPARTAN/trunk/ MIPS architecture now works without any problems in
- msim: compile as OUTPUT_FORMAT(binary)
- gxemul: compile as OUTPUT_FORMAT(ecoff-littlemips), or create
configuration file for binary format (will be done later)
- simics: compile as OUTPUT_FORMAT(elf32-little), might work with binary
format, didn't try yet.		  
268 6814 d 8 h palkovsky /SPARTAN/trunk/ Added symbol table lookup in exceptions.
This breaks ia64 & ppc architecture compiles.		  
216 6817 d 1 h palkovsky /SPARTAN/trunk/ hardcoded_symbol fixed into linker script on amd64/ia32/mips architecture  
130 6859 d 13 h decky /SPARTAN/trunk/arch/mips/ Make MIPS target compile and link properly with the new 4.0.1 MIPS toolchain  
125 6864 d 3 h jermar /SPARTAN/trunk/ Huge indentation fix.  
111 6903 d 5 h palkovsky /SPARTAN/trunk/ Code cleanup in scheduler.c thread.c - removed unnecessary spinlock.
atomic_inc, atomic_dec moved to arch/atomic.h instead of arch/smp/atomic.h,
advisable to use even in non-smp mode.
Fixed atomic_inc, atomic_dec in mips architecture.		  
106 6906 d 11 h jermar /SPARTAN/trunk/ IA-32 fixes.
Use kernel addresses instead of physical addresses in map_page_to_frame().
Physical addresses are supposed to only be exported to mm hardware.
Because of this fix, userspace is functional again.

Remap EGA videoram to (0x80000000 + videoram) and change the ega driver to work with the new address.

Minor cosmetics through out the code.
Changes in linker scripts.
