to DP and AP registers through a conceptual queue of operations.
- Builds the first implementation of such a transport with the existing
JTAG-specific code.
In contrast to the current JTAG-only interface, the interface adds
support for two previously-missing (and unused) DAP operations:
- aborting the current AP transaction (untested);
- reading the IDCODE register (tested) ... required for SWD init.
The choice of transports may be fixed at the chip, board, or JTAG/SWD
adapter level. Or if all the relevant hardware supports both transport
options, the choice may be made at runtime, This patch provides basic
infrastructure to support whichever choice is made.
The current "JTAG-only" transport choice policy will necessarily continue
