63 Add support for Xilinx ISim Verilog simulator.
Remove Virtex-6 files.		 csantifort 4454d 21h /amber/trunk/hw/tools/
61 Add new netowkr based boot loader.
Remove support for Virtex. Spartan 6 only now.		 csantifort 4741d 16h /amber/trunk/hw/tools/
56 Remove the timeouts file from svn. Its an output file and gets now just gets created automatically
when sims are run for the first time.		 csantifort 5029d 13h /amber/trunk/hw/tools/
54 Bug fix for bug reported by Botao Lee. The mode bits in the decode stage did not change immediately
after a mode switch from a teqp instruction, but 1 cycle later. This meant the wrong set of registers
was selected for writing to for 1 clock cycle.		 csantifort 5046d 12h /amber/trunk/hw/tools/
48 Fixed a bug in linux that caused the os to not return to the running application after an interrupt.
Hello-world now runs stand-alone again.
Added initrd-200k-dhry, a disk image that uses the dhry program for init.		 csantifort 5106d 17h /amber/trunk/hw/tools/
45 Store vmlinux.mem and vmlinux.dis in compressed form csantifort 5134d 12h /amber/trunk/hw/tools/
40 Added wishbone bus jitter testing option.
Cleaned up waveform log .do files, now seperate files for a23 and a25 cores.
Added vmlinux executable elf file for running on hardware.		 csantifort 5158d 10h /amber/trunk/hw/tools/
36 Changed boot_mem for the a25 system to be 128 bits wide to match the 128-bit wide wishbone bus csantifort 5161d 10h /amber/trunk/hw/tools/
35 Amber25 improvements:
Use 128-bit wishbone bus, instead of 32-bit to reduce cache miss fetch times
Use a fast barrel shifter for shifts between 0 and 4 to improve timing
Use a 2 cycle full barrel shifter for complex shifts		 csantifort 5162d 17h /amber/trunk/hw/tools/
29 Use lgo command for saving waveforms in modelsim csantifort 5180d 10h /amber/trunk/hw/tools/
25 Bug fix: boot-loader.mem became larger that the allowed 8k byte boot mem size.
Removed a struct in elfsplitter.c thats only used for debug - this reduced boot-loader.mem enough so that it fits again.
Tidy up: Removed a debug message from hw/tools/run.sh		 csantifort 5220d 15h /amber/trunk/hw/tools/
20 Added feature to A25 core to directly use a read value from the write back stage
to reduce the stall to 1 cycle when there is a register conflict with the
following instruction. This increases performance by about 3%.		 csantifort 5247d 16h /amber/trunk/hw/tools/
17 amber25 core bug fix. The return address for irq interrupts was off by 4 bytes
when the interrupt occurred during a stm instruction with the following instruction
having some register conflicts. Added test irq_stm to catch the bug.
Cleaned up some header descriptions		 csantifort 5251d 14h /amber/trunk/hw/tools/
15 Copied amber to amber23, Many system changes to support new amber25 core. csantifort 5254d 05h /amber/trunk/hw/tools/
11 Added vmlinux test. csantifort 5270d 17h /amber/trunk/hw/tools/
2 Baseline release of the Amber 2 core csantifort 5284d 15h /amber/trunk/hw/tools/
