This - I believe - at the hardware level will need some new access
functions.
For example - today - all interfaces are controlled via function
pointers in:
typedef struct jtag_interface_s jtag_interface_t;
None of those act, or think, or look like the hardware SWJ interface -
or that is my impression.
I could be *very* wrong.
I mention this because a while ago I thought it would be nice to have
OpenOCD setup to program SPI flash chips directly.
In what Xlinix calls serial spi mode.
In effect, one could
(a) rename:
old: jtag_itnerface_t::execute_que()
new: jtag_interface_t:: execute_jtag_que()
(b) Add:
jtag_interface_t:execute_spi_que()
and jtag_interface_t::execute_i2c_que()
and in your specific case....
.. perhaps jtag_interface_t::execute_swj_que()
It is a thought... I have not gone further then a pipe dream.
