@subsection thelistadapterrework Code restructuring
This section lists pending reworks to complete the restructure from the
old JTAG centric implementation to a generic Adapter layer.
This restructuring is very invasive and will prevent the merge of several
changes pending in gerrit.
- rename folder src/jtag/ to src/adapter/
- rename var "jtag" to "adapter" in src/jtag/core.c
- split content of src/adapter/ in the different protocols jtag.[ch],
swd.[ch], ...
- wrap the calls to adapter->transport_ops->api() with transport_api()
and reduce the visibility of global var "adapter"
- complete the migration of JTAG-only drivers to adapter->reset()
- try to remove JTAG_SLEEP also from JTAG mode?
- tap_set_state(TAP_RESET) is already done in src/jtag/core.c. No need
to replicate it in the drivers, apart in case the driver sets TRST
independently
- separate SWIM from HLA and make it independent
- add .hla_ops and .swim_ops to "adapter"
- HLA is a API level (.hla_ops). Transport should simply be {jtag,swd},
not {hla_jtag,hla_swd}.
