-- gerrit commit 2473d691348eb80476225502158c53fcc54113c0 Author: Matthias Welwarsky <[email protected]> Date: Tue Oct 13 12:02:58 2015 +0200 AM335x: allow simultaneous debugging of A8 and M3 cores This patch fixes the tap order so that it matches the actual jtag chain when all taps are enabled. It also introduces a variable DEFAULT_TAPS that can be set outside of this script, e.g. on the command line, to specify which taps are to be enabled on init. Lastly, a new debug target "am335x.m3" is added so that the Wakeup-M3 can be selected for debugging.
