- add 'dap create' command to create dap instances - move all dap subcmmand into the dap instance commands - keep 'dap info' for convenience - change all armv7 and armv8 targets to take a dap instance instead of a jtag chain position - restructure tap/dap/target relations, jtag tap no longer references the dap, daps are now independently created and initialized. - clean up swd connect - re-initialize DAP also on JTAG errors (e.g. after reset, power cycle) - update documentation - update target files Change-Id: I322cf3969b5407c25d1d3962f9d9b9bc1df067d9 Signed-off-by: Matthias Welwarsky <matthias.welwarsky@sysgo.com> Reviewed-on: http://openocd.zylin.com/4468 Tested-by: jenkins Reviewed-by: Matthias Welwarsky <matthias@welwarsky.de>
