61 Add new netowkr based boot loader.
Remove support for Virtex. Spartan 6 only now.		 csantifort 4667d 14h /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 4955d 11h /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 4972d 11h /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 5032d 15h /amber/trunk/hw/tools/
45 Store vmlinux.mem and vmlinux.dis in compressed form csantifort 5060d 11h /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 5084d 08h /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 5087d 08h /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 5088d 16h /amber/trunk/hw/tools/
29 Use lgo command for saving waveforms in modelsim csantifort 5106d 09h /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 5146d 14h /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 5173d 15h /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 5177d 13h /amber/trunk/hw/tools/
15 Copied amber to amber23, Many system changes to support new amber25 core. csantifort 5180d 03h /amber/trunk/hw/tools/
11 Added vmlinux test. csantifort 5196d 16h /amber/trunk/hw/tools/
2 Baseline release of the Amber 2 core csantifort 5210d 14h /amber/trunk/hw/tools/
