workflow for issuing a suggested patch, please (ARC processor)

[Jon Nicoll]

Hi there
    I am (trying to!) use OpenOCD on a Synopsys ARC processor on an 
FPGA. Whilst trying to figure out a problem I am seeing relating to 
address auto-incrementing, I came across and hopefully fixed another 
small problem in openOCD for the ARC.

This is due to the fact that newer versions of the Synopsys ARC EM4 have 
new possible values for some XXX_BUILD register fields. OpenOCD doesn't 
know about these new values and mis-configures its knowledge of the DCCM 
and ICCM available (Closely-Coupled Data and Instruction Memory). This 
in turn affects the fine detail of memory read and writes via OpenOCD.

I have made some small .c and .tcl changes which I think fix this. This 
has not helped with my original problem but I would like to contribute 
this change to OpenOCD. I'm unsure of the process though, can someone 
point me at some guidelines? Do I need to (say) raise a ticket first, 
and then upload a patch against that ticket?

    Thanks & Regards
