43	Added support for the flat executable file format to vmlinux, so that the hello-world program is correctly relocated when it is loaded at the end of the vmlinux test. Changed the Virtex-5 clock configuration to use a 1200MHz VCO frequency and 80MHz system clock frequency.	csantifort	4766d 13h	/
42	Added write buffer - fixes bug if wishbone writes takes multiple cycles to complete	csantifort	4784d 10h	/
41	Added instructions on how to use Coregen to create the Spartan-6 DDR3 memory interface.	csantifort	4785d 18h	/
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	4790d 11h	/
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	4791d 11h	/
38	support 128-bit wishbone now used for a25 core	csantifort	4792d 11h	/
37	128-bit wide boot memory module	csantifort	4793d 09h	/
36	Changed boot_mem for the a25 system to be 128 bits wide to match the 128-bit wide wishbone bus	csantifort	4793d 10h	/
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	4794d 18h	/
34	Tweaked strcpy function to speed it up slightly	csantifort	4795d 14h	/
33	Fixed bug in div assembly function. Handles negative numbers correctly. Fixed bug in printf function, negative numbers now print correctly.	csantifort	4796d 11h	/
32	Added clock cycle counting register to test_module to support dhrystone performance measurement	csantifort	4797d 11h	/
31	Added dhrystone benchmark test	csantifort	4797d 11h	/
30	Bug fix - a write access was sometimes dropped when it was in a sequence of writes with variable wb_ack delays	csantifort	4810d 18h	/
29	Use lgo command for saving waveforms in modelsim	csantifort	4812d 11h	/
28	Moved function prototypes to .h file	csantifort	4812d 12h	/
27	Got working with cadence nc simulator	csantifort	4845d 19h	/
26	Added wish list	csantifort	4850d 19h	/
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	4852d 16h	/
24	Added instructions how to build Linux kernel from source files	csantifort	4854d 16h	/
