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 4984d 03h /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 4987d 03h /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 4988d 11h /amber/trunk/hw/tools/
29 Use lgo command for saving waveforms in modelsim csantifort 5006d 04h /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 5046d 09h /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 5073d 10h /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 5077d 08h /amber/trunk/hw/tools/
15 Copied amber to amber23, Many system changes to support new amber25 core. csantifort 5079d 22h /amber/trunk/hw/tools/
11 Added vmlinux test. csantifort 5096d 10h /amber/trunk/hw/tools/
2 Baseline release of the Amber 2 core csantifort 5110d 09h /amber/trunk/hw/tools/
