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 4898d 11h /amber/trunk/hw/tests/
50 Revert to previous version csantifort 4954d 09h /amber/trunk/hw/tests/
49 Added a note n how to change timeouts csantifort 4954d 09h /amber/trunk/hw/tests/
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 4958d 16h /amber/trunk/hw/tests/
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 5010d 09h /amber/trunk/hw/tests/
36 Changed boot_mem for the a25 system to be 128 bits wide to match the 128-bit wide wishbone bus csantifort 5013d 08h /amber/trunk/hw/tests/
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 5014d 16h /amber/trunk/hw/tests/
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 5099d 15h /amber/trunk/hw/tests/
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 5103d 13h /amber/trunk/hw/tests/
15 Copied amber to amber23, Many system changes to support new amber25 core. csantifort 5106d 04h /amber/trunk/hw/tests/
11 Added vmlinux test. csantifort 5122d 16h /amber/trunk/hw/tests/
6 Set ignore property for output files csantifort 5135d 13h /amber/trunk/hw/tests/
2 Baseline release of the Amber 2 core csantifort 5136d 14h /amber/trunk/hw/tests/
