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 5114d 08h /amber/trunk/hw
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 5116d 09h /amber/trunk/hw
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 5120d 08h /amber/trunk/hw
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 5141d 09h /amber/trunk/hw
19 Create a configuration log file as part of the synthesis flow. This file is a useful reference to
tell the different bitfiles apart.		 csantifort 5141d 09h /amber/trunk/hw
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 5145d 07h /amber/trunk/hw
16 Deleted the old version of the 3-state amber core. Its replaced with amber23.
Added the 5-state Amber core.		 csantifort 5147d 21h /amber/trunk/hw
15 Copied amber to amber23, Many system changes to support new amber25 core. csantifort 5147d 21h /amber/trunk/hw
14 Re-wrote the behavioral clock generation code to more accurately
calculate the sys_clk frequency. The previous version was not
producing the correct frequency at higher frequenies due to
rounding errors.		 csantifort 5149d 09h /amber/trunk/hw
13 Bug fix - added an extra state to the rx state machine to properly align
reading the uart input to the middle of each bit.		 csantifort 5149d 09h /amber/trunk/hw
12 Added INITIALIZE_TO_ZERO parameter to keep instantiation
idendical to generic sram models. The parameter is not used
in the Xilinx models (they always init to zero) but it used
in the generic models.		 csantifort 5149d 10h /amber/trunk/hw
11 Added vmlinux test. csantifort 5164d 10h /amber/trunk/hw
10 Removed parameters for unused peruipheral modules csantifort 5165d 13h /amber/trunk/hw
9 Change the format of mcr and mrc listings so they exactly match the dissasembly produced by the gnu tools.
Write ip instead of r12 in listings.		 csantifort 5165d 13h /amber/trunk/hw
8 Change the value in the ID register to be compatible with the Linux code that parses it and picks a processor type. csantifort 5165d 13h /amber/trunk/hw
7 Added instructions to use Veritak simulator.
Removed some unused functions from memory_configuration.v.		 csantifort 5174d 04h /amber/trunk/hw
6 Set ignore property for output files csantifort 5177d 07h /amber/trunk/hw
5 Deleted two temporary files that should not be in the release. csantifort 5178d 03h /amber/trunk/hw
2 Baseline release of the Amber 2 core csantifort 5178d 08h /amber/trunk/hw
