42	Added write buffer - fixes bug if wishbone writes takes multiple cycles to complete	csantifort	4979d 20h	/amber/trunk/
41	Added instructions on how to use Coregen to create the Spartan-6 DDR3 memory interface.	csantifort	4981d 05h	/amber/trunk/
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	4985d 21h	/amber/trunk/
39	Added a second level of buffering to a25_wishbone_buf to fix a lockup bug when write acks to not return immediately, and also to improve performance slightly	csantifort	4986d 22h	/amber/trunk/
38	support 128-bit wishbone now used for a25 core	csantifort	4987d 22h	/amber/trunk/
37	128-bit wide boot memory module	csantifort	4988d 20h	/amber/trunk/
36	Changed boot_mem for the a25 system to be 128 bits wide to match the 128-bit wide wishbone bus	csantifort	4988d 21h	/amber/trunk/
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	4990d 05h	/amber/trunk/
34	Tweaked strcpy function to speed it up slightly	csantifort	4991d 01h	/amber/trunk/
33	Fixed bug in div assembly function. Handles negative numbers correctly. Fixed bug in printf function, negative numbers now print correctly.	csantifort	4991d 22h	/amber/trunk/
32	Added clock cycle counting register to test_module to support dhrystone performance measurement	csantifort	4992d 22h	/amber/trunk/
31	Added dhrystone benchmark test	csantifort	4992d 22h	/amber/trunk/
30	Bug fix - a write access was sometimes dropped when it was in a sequence of writes with variable wb_ack delays	csantifort	5006d 04h	/amber/trunk/
29	Use lgo command for saving waveforms in modelsim	csantifort	5007d 22h	/amber/trunk/
28	Moved function prototypes to .h file	csantifort	5007d 23h	/amber/trunk/
27	Got working with cadence nc simulator	csantifort	5041d 05h	/amber/trunk/
26	Added wish list	csantifort	5046d 06h	/amber/trunk/
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	5048d 03h	/amber/trunk/
24	Added instructions how to build Linux kernel from source files	csantifort	5050d 03h	/amber/trunk/
23	Split the source files list into a Vertex-6 only list and a Spartan-6 only list. That way users don;t need to delete files from the list manually if they only have a setup for one of the FPGA types.	csantifort	5050d 04h	/amber/trunk/
