49 Added a note n how to change timeouts csantifort 4995d 09h /amber/trunk/
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 4999d 15h /amber/trunk/
47 Changed V6 VCo from 1000Mhz to 1200 MHz csantifort 5019d 13h /amber/trunk/
46 svn ignore vmlinux.dis and vmlinux.mem csantifort 5027d 10h /amber/trunk/
45 Store vmlinux.mem and vmlinux.dis in compressed form csantifort 5027d 10h /amber/trunk/
44 Updated vmlinux image based on last change csantifort 5027d 11h /amber/trunk/
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 5027d 11h /amber/trunk/
42 Added write buffer - fixes bug if wishbone writes takes multiple cycles to complete csantifort 5045d 07h /amber/trunk/
41 Added instructions on how to use Coregen to create the Spartan-6 DDR3 memory interface. csantifort 5046d 16h /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 5051d 08h /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 5052d 09h /amber/trunk/
38 support 128-bit wishbone now used for a25 core csantifort 5053d 09h /amber/trunk/
37 128-bit wide boot memory module csantifort 5054d 07h /amber/trunk/
36 Changed boot_mem for the a25 system to be 128 bits wide to match the 128-bit wide wishbone bus csantifort 5054d 08h /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 5055d 16h /amber/trunk/
34 Tweaked strcpy function to speed it up slightly csantifort 5056d 12h /amber/trunk/
33 Fixed bug in div assembly function. Handles negative numbers correctly.
Fixed bug in printf function, negative numbers now print correctly.		 csantifort 5057d 08h /amber/trunk/
32 Added clock cycle counting register to test_module to support dhrystone performance measurement csantifort 5058d 09h /amber/trunk/
31 Added dhrystone benchmark test csantifort 5058d 09h /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 5071d 15h /amber/trunk/
29 Use lgo command for saving waveforms in modelsim csantifort 5073d 09h /amber/trunk/
28 Moved function prototypes to .h file csantifort 5073d 10h /amber/trunk/
27 Got working with cadence nc simulator csantifort 5106d 16h /amber/trunk/
26 Added wish list csantifort 5111d 16h /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 5113d 14h /amber/trunk/
24 Added instructions how to build Linux kernel from source files csantifort 5115d 14h /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 5115d 15h /amber/trunk/
22 Added files and instructions to enable the building of the vmlinux image from the kernel source files. csantifort 5119d 14h /amber/trunk/
21 Fixed bug in the conditions to create the FPGA configuration log file. I added the creation of the log file in the last release, but the way it was implemented was causing the Makefile to always rebuild from the start. csantifort 5119d 14h /amber/trunk/
