We have just created a DE2 port of ORPSoC. It is based on DE1 port, pin mapping and pll was altered. It works now as some simple programs such as HelloWorld can be run, but it may be not be completed and need more testing and updates.

Remove generic system
35d07c2 
The generic system has been broken for a long time and only adds
confusion. It has been more or less replaced with or1200-generic

Thanks for this. Just wondering when you say that it works for simple programs. Have you tried it on a real DE2 board, or only in simulation?

No error while using Icarus but Modelsim complains.

Add missing stdlib.h and ctype.h required for NULL, free() and
isspace().

@olofk
The man who wrote this DE2 port tested it on his DE2-70 Board. I saw it worked with timerled (from orconf2013) and HelloWorld program (https://code.google.com/p/vak-opensource/source/browse/trunk/hardware/s3esk-openrisc/hello-uart/hello.c) . Did it work to you?

@fjullien
Newly generated wb_intercon.v and wb_intercon.vh still doesn't include wb8_xxx signals as in my most recent commit.

Yeah I'm sorry I did a mistake. wb8_xx signals are not created. However, the wb_resize is now included in the generated interconnection.

Anyway, may be I pull this request too soon, there are a lot of problems in my orpsoc-cores repo now as it have some error after updated from the parent repo. May be I should put another one when I finished fix them.

@tmd-set I haven't got a de2 board myself, but I trust you if you say it works. Great job!
The pull request has become a bit messy however, so when you have fixed the things that @fjullien commented on, it might be best to just do a new pull request
