Hi Duane,

Your MUA is apparently doing strange things:

1. Weird quotation style (or is it you doing it manually?);

2. Whole paragraphs without line breaks (i.e. you end up with one line
per paragraph).

Not that it matters much but it's still a bit inconvenient and kind of
strange given that plain/text format and emails using it are
well-established and universally supported.

What if OpenOCD would expose JTAG_AP ports via a regular socket with a
JTAG-level protocol (i.e. a bit higher than bitbang; is there any
known specification we could reuse?) and another OpenOCD instance
would have an interface adapter driver that would be a client for that
protocol? That would probably be simpler than to teach a single
OpenOCD process to work with multiple JTAG chains at the same time.

Is your current plan to allocate an independent "dap" struct per every
DAP, each holding pointer to the transport used for its access and
targets having pointers to those DAP structures? It seems that would
look like a sane layering matching real hardware; are you aware with
any downsides of this approach yet, any nasty inter-dependencies I'm
not aware of?
