AVR support for gdb 5.x

[Roland Zitzke]

Hi,
I am new to this list so please apologize if this 
issue has been discussed before.
For gdb 4.18 there was a pathch for the Atmel AVR 
microcontroller written by Denis Chertykov. I haven't seen any AVR support in 
the latest (5.0) gdb version.
I tried to port the patch to gdb 5 but I 
encountered several issues about changed macro and function definitions. 
Therefore I want to make sure no one else has already done this job before I 
spend more time on it.
The patch relys on a special monitor connected via 
a TCP port.
This monitor software then uses a proprietary 
connection scheme on the PCs parallel port which is frequently used to connect 
Atmel AVR controllers.
