326	6823 d 17 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.		/SPARTAN/trunk/arch/mips/_link.ld.in /SPARTAN/trunk/test/fpu/mips1 /SPARTAN/trunk/test/fpu/mips1/test.c /SPARTAN/trunk/arch/mips/_link.ld /SPARTAN/trunk/arch/amd64/Makefile.inc /SPARTAN/trunk/arch/amd64/src/fpu_context.c /SPARTAN/trunk/arch/ia32/Makefile.inc /SPARTAN/trunk/arch/ia64/Makefile.inc /SPARTAN/trunk/arch/mips/Makefile.inc /SPARTAN/trunk/arch/mips/boot/boot.S /SPARTAN/trunk/arch/mips/include/asm.h /SPARTAN/trunk/arch/mips/include/asm/boot.h /SPARTAN/trunk/arch/mips/include/byteorder.h /SPARTAN/trunk/arch/mips/include/cp0.h /SPARTAN/trunk/arch/mips/include/exception.h /SPARTAN/trunk/arch/mips/include/fpu_context.h /SPARTAN/trunk/arch/mips/include/thread.h /SPARTAN/trunk/arch/mips/src/asm.S /SPARTAN/trunk/arch/mips/src/console.c /SPARTAN/trunk/arch/mips/src/dummy.S /SPARTAN/trunk/arch/mips/src/exception.c /SPARTAN/trunk/arch/mips/src/fpu_context.c /SPARTAN/trunk/arch/mips/src/mips.c /SPARTAN/trunk/arch/mips/src/mm/frame.c /SPARTAN/trunk/arch/mips/src/panic.S /SPARTAN/trunk/arch/mips/src/start.S /SPARTAN/trunk/arch/ppc/Makefile.inc /SPARTAN/trunk/contrib/conf/msim.conf /SPARTAN/trunk/src/Makefile /SPARTAN/trunk/src/build.mips /SPARTAN/trunk/src/clean.mips
