[ros-dev] [ros-diffs] [fireball] 50967: - Revert 47615. Please fix actual sysreg instead of adding inconsistency between 1st, 2nd and 3rd stages debugging connections. This should fix sysreg3's inability to do backtrace...

[Aleksey Bragin]

Yes, throughout all years I used to type into the virtual machine  
window (or real hardware's keyboard) in order to enter kdbg commands  
in 1st, 2nd and 3rd stages. The default way for 2nd and 3rd remains  
the same, but that commit changed default for the 1st stage, and that  
was quite unexpected (there was even a bug report submitted for  
that). Not to say that I didn't notice that commit back then, and was  
wondering why sysreg3 is not able to enter any kdbg commands into  
virtual box window when first stage of setup runs.
