[Simulavr-devel] New feature: read in signatue, lock bits and fuses from elf, if available

[ThomasK]

Hi list,

now I had a little bit time to start a task, which was in my inbox for a 
longer time: a suggestion from Petr to read and use controller signature.

I've started now to implement this. If simulavr commandline application 
read a given elf file, it reads now too signature, fuses and lock bits 
area, if available. In this first step it compares then signature from 
elf to controller signature, which is selected by "-d" option on 
commandline. If a signature is available on elf and not equal to 
selected controller signature, it aborts.

One question is, is there a need to disable this feature? (maybe on 
avr-libc tests?) Of course, some simple programs, which are compiled an 
linked for example for mega16 will also work for mega32. On the other 
hand, I don't want to implement useless "features". :-)

In the moment, this code resides in my repository, if someone wants to 
review it or try it, I can upload it in a development branch. Please let 
me know, if I should do this.

Planed next step is, to extend (E)LPM instruction to read - depending on 
controller - fuses, lockbits and signature by program.

cu, Thomas
