Re: JTAG debug support for ARM

I do not believe that there is any question of legality.   Gdb
is commonly used with libraries that are not available as 
source.   For example; running it on Solaris, etc.   What
about if I bought the accelerated X server that Red Hat
sold.   Must I not run gdb?

The Linux community recognizes that to win in the public
arena some software will not be GPL'ed.   Indeed, most
people actively encourage commercial software to be
ported to Linux.

I have written GLP'ed software and I have written commercial 
software.  This project gives me the opportunity to give to the Linux
community something that previously was only available
under Windows.
