Only missing items (to be added soon):

Currently have to be added manually to some CPUID model, for example to ICL-U

2a55ba0a39 Merge set of debugger improvements by Doug Gale <doug16k> 
Here is his original comment:

I have made several improvements in the debugger.
I have fixed several issues with proper handling of 64-bit addresses, and added support for 64 bit symbols.
I also have added several symbol lookups.
