165	Added (very early draft, very incomplete) reserved opcode trap handler. Updated opcode tester to test some emulated mips32 opcodes using the trap handler.	ja_rd	4786d 09h	/ion/
164	Minor typo fixes in source file	ja_rd	4786d 09h	/ion/
163	SW simulator update: Better disassembly format (hastily tested) New parameters: start address, breakpoint address, whether or not to trap reserved opcodes	ja_rd	4786d 10h	/ion/
162	Fixed stupid mistake in headers (date of project)	ja_rd	4787d 01h	/ion/
161	Added GPL license info to the vhdl headers This project is becoming respectable :)	ja_rd	4787d 02h	/ion/
160	BUG FIX: the cache init code was messing the BSS initialization	ja_rd	4788d 03h	/ion/
159	bug detected but not fixed in cpu (1st instruction after entering user mode is executed in kernel mode)	ja_rd	4788d 10h	/ion/
158	removed file from TB directory which was committed by mistake	ja_rd	4788d 10h	/ion/
157	Bug fix in the missing coprocesor exception. The CPU was triggering a privilege exception for the mtc0 that went into user mode. Logging HDL updated	ja_rd	4789d 20h	/ion/
156	project doc somewhat updated (but still out of date)	ja_rd	4790d 04h	/ion/
155	Temporary warning added to outdated project doc file	ja_rd	4790d 05h	/ion/
154	fixed log trigger address in hello makefile	ja_rd	4790d 05h	/ion/
153	Added R3000 compatible support for kernel/user state: - Implemented KU/IE plus KUp/IEp and KUo/IEo status bits - Updated startup and test code to account for changes - Implemented bit DID NOT TEST rfe instruction (not used in code) - Access to CP0 in user mode triggers 'CpU' trap - Updated software simulator Besides, the logging of HI/LO register changes has been temporarily disabled, there's an unfixed bug in it.	ja_rd	4790d 05h	/ion/
152	Added R3000 compatible support for kernel/user state: - Implemented KU/IE plus KUp/IEp and KUo/IEo status bits - Updated startup and test code to account for changes - Implemented bit DID NOT TEST rfe instruction (not used in code) - Access to CP0 in user mode triggers 'CpU' trap - Updated software simulator Besides, the logging of HI/LO register changes has been temporarily disabled, there's an unfixed bug in it.	ja_rd	4790d 05h	/ion/
151	BUG FIX: major bugs fixed in cache module 1.- sram address was wrong (leftover from previous version) 2.- writes to unmapped areas were blocking the cache 3.- Sequence SW,LW produced a RAW data hazard in some cases	ja_rd	4790d 06h	/ion/
150	Bug fix: added missing nop in vacant branch delay slot	ja_rd	4791d 03h	/ion/
149	changed size of simulated flash in opcodes sample code	ja_rd	4791d 03h	/ion/
148	Added optional cache support to 'opcodes' test. Updated simulation length accordingly.	ja_rd	4792d 19h	/ion/
147	SW simulator updated to latest HW revision (plus a few mistakes corrected: wrongly commented out lines, mostly)	ja_rd	4792d 19h	/ion/
146	Added D-Cache setup code to 'adventure' bootstrap code (redundant since common C startup code already does it but...)	ja_rd	4792d 20h	/ion/
