244 New link script that puts everything on XRAM (16-bit SRAM on the DE-1 board).
Programs linked with this script will have to be 'bootloaded' on RAM.		 ja_rd 4256d 16h /ion/trunk/src/common/
243 Added a port of ElmChan's FatFS library for the DE-1 board.
Uses bit-banged SPI interface so it should be trivially easy to port to other boards.		 ja_rd 4256d 16h /ion/trunk/src/common/
238 BUG FIX: C startup code that copied initialized data to data section was wrong when initialized data was not a multiple of 4 bytes. ja_rd 4256d 21h /ion/trunk/src/common/
236 Added macros to SoC header file for easy access to GPIO registers ja_rd 4257d 18h /ion/trunk/src/common/
229 Code samples updated to use new VHDL config packages and new SoC (UART). ja_rd 4404d 23h /ion/trunk/src/common/
184 Updated some application makefiles to make use of common makefile ja_rd 4770d 06h /ion/trunk/src/common/
183 Updated comments and readme file for code samples ja_rd 4771d 22h /ion/trunk/src/common/
181 Bug fix: left out a link script in last commit ja_rd 4771d 22h /ion/trunk/src/common/
180 Removed old support code
Bits of it may yet reappear as part of the new support library		 ja_rd 4772d 09h /ion/trunk/src/common/
178 Added FP math support to support library
Uses code lifted from old version of GNU libc, no adaptation needed
NEEDS testing!		 ja_rd 4772d 09h /ion/trunk/src/common/
175 Updated support library
Removed spurious dependence to accursed '_impure_ptr'		 ja_rd 4772d 09h /ion/trunk/src/common/
174 started to add branch emulation to opcode emulator ja_rd 4772d 10h /ion/trunk/src/common/
173 New version of support code, still incomplete. ja_rd 4772d 10h /ion/trunk/src/common/
172 Added new version of support code, still incomplete ja_rd 4774d 00h /ion/trunk/src/common/
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 4780d 23h /ion/trunk/src/common/
164 Minor typo fixes in source file ja_rd 4780d 23h /ion/trunk/src/common/
160 BUG FIX: the cache init code was messing the BSS initialization ja_rd 4782d 17h /ion/trunk/src/common/
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 4784d 19h /ion/trunk/src/common/
144 Added cache setup code to common startup code
Important: the new cache won't work without this		 ja_rd 4787d 09h /ion/trunk/src/common/
131 change to local system-dependent directory path ja_rd 4792d 14h /ion/trunk/src/common/
130 typo fix ja_rd 4792d 14h /ion/trunk/src/common/
91 FIX: startup files can now be used to run from FLASH or BRAM ja_rd 4891d 18h /ion/trunk/src/common/
89 Added startup and utility functions for 'bare metal' applications running from FLASH, plus linker file ja_rd 4891d 18h /ion/trunk/src/common/
88 Added UART RX interface to MPU template ja_rd 4891d 18h /ion/trunk/src/common/
66 Code samples:
Updated all code samples to use TB2 template and new memory map		 ja_rd 4902d 08h /ion/trunk/src/common/
34 default data address moved to 0x80000000
makefiles and readme files updated accordingly		 ja_rd 4908d 18h /ion/trunk/src/common/
2 First commit (includes 'hello' demo) ja_rd 4913d 21h /ion/trunk/src/common/
