-- JTAG/TAP changes:
- - update all drivers to use tap_get_tms_path_len API.
- - use tap_set_state everywhere to allow logging TAP state transitions
- - rename other tap_states to use standard JTAG names (suggested by ML)
- - retire jtag_add_end_state() and replace w/global variable. This also
- removes TAP_INVALID as an argument to jtag_add_xxxx(). The global variable
- as argument to jtag_add_xxxx() should eventually be phased out, but
- the global variable is useful in an interim phase where one needs to
- be bug by bug compatible before each change can be tested. Suggested
- by ØH. Michael Bruck also interested in this.

-- CFI:

- - factor vendor-specific code into separate source files
+@section thelisttcl TCL
+
+This section provides possible things to improve with OpenOCD's TCL support.
+
+- organize the TCL configurations:
+ - provide more directory structure for boards/targets?
+ - factor configurations into layers (encapsulation and re-use)
+
+- Isolate all TCL command support:
+ - Pure C CLI implementations using --disable-builtin-tcl.
+ - Allow developers to build new dongles using OpenOCD's JTAG core.
+ - At first, provide only low-level JTAG support; target layer and
+ above rely heavily on scripting event mechanisms.
+ - Allow full TCL support? add --with-tcl=/path/to/installed/tcl
+ - Move TCL support out of foo.[ch] and into foo_tcl.[ch] (other ideas?)
+
+@section thelistjtag JTAG
+
+This section list issues that need to be resolved in the JTAG layer.
+
+@subsection thelistjtagcore JTAG Core
+
+The following tasks have been suggeted for cleaning up the JTAG layer:
+
+- use tap_set_state everywhere to allow logging TAP state transitions
+- rename other tap_states to use standard JTAG names (suggested by ML)
+- retire jtag_add_end_state() and replace w/global variable:
+ - removes TAP_INVALID as an argument to jtag_add_xxxx().
+ - global variable as argument to jtag_add_xxxx() should be phased out, but
+ it is useful while we need to bug-by-bug compatible while testing changes.
+ - Suggested by ØH. Michael Bruck also interested in this.
+- Encapsulate cmd_queue_cur_state and related varaible handling.
+
+The following tasks have been suggested for adding new core JTAG support:
+
+- autodetect devices present on the scan chain
+ - implement 'discover_taps' command
+- SPI/UART emulation:
+ - (ab)use bit-banging JTAG interfaces to emulate SPI/UART
+ - allow SPI to program flash, MCUs, etc.
+
+@subsection thelistjtaginterfaces JTAG Interfaces
+
+The following tasks have been suggeted for improving OpenOCD's JTAG
+interface support:
+
+- rework USB communication to be more robust. Two possible options are:
+ -# use libusb-1.0.1 with libusb-compat-0.1.1 (non-blocking I/O wrapper)
+ -# rewrite implementation to use non-blocking I/O
+- FT2232 driver:
+ - integrate FTD2XX High-Speed Device support @par
+ PATCH: https://lists.berlios.de/pipermail/openocd-development/2009-April/005479.html
+ - fix outstanding bugs
+- J-Link driver:
+ - fix to work with long scan chains, such as R.Doss's svf test.
+ - fix other outstanding bugs
+
+The following tasks have been suggested for adding new JTAG interfaces:
+
+- TCP driver: allow client/server for remote JTAG interface control.
+
+@section thelistswd Serial Wire Debug
+
+- implement Serial Wire Debug interface
+
+@section thelistbs Boundary Scan Support
+
+- add STAPL support?
+- add BSDL support?
+
+A few possible options for the above:
+ -# Fake a TCL equivalent?
+ -# Integrate an existing library?
+ -# Write a new C implementation a la Jim?
+
+Once the above are completed:
+- add support for programming flash using boundary scan techniques
+- add integration with a modified gerber view program:
+ - provide means to view the PCB and select pins and traces
+ - allow use-cases such as the following:
+ - @b Stimulus
+ -# Double-click on a pin (or trace) with the mouse.
+ - @b Effects
+ -# The trace starts blinking, and
+ -# OpenOCD toggles the pin(s) 0/1.
+
+@section thelisttargets Target Support
+
+- general layer cleanup:
+ - https://lists.berlios.de/pipermail/openocd-development/2009-May/006590.html

+- investigate/implement "thin wrapper" to use eCos CFI drivers (ØH)
+
+@section thelistdebug Debugger Support
+
+- integrate Keil AGDI interface to OpenOCD? (submitted by Dario Vecchio)
+
+@section thelisttesting Testing Suite
+
+This section includes several related groups of ideas:
+- @ref thelistunittests
+- @ref thelistsmoketests
+- @ref thelisttestreports
+- @ref thelisttestgenerichw
+
+@subsection thelistunittests Unit Tests
+
+- add testing skeleton to provide frameworks for adding tests
+- implement server unit tests
+- implement JTAG core unit tests
+- implement JTAG interface unit tests
+- implement flash unit tests
+- implement target unit tests
+
+@subsection thelistsmoketests Smoke Test Tools
+
+-# extend 'make check' with a smoketest app
+ - checks for OOCD_TEST_CONFIG, etc. in environment (or config file)
+ - if properly set, runs the smoke test with specified parameters
+ - openocd -f ${OOCD_TEST_CONFIG}
+ - implies a modular test suite (see below)
+ - should be able to run some minimal tests with dummy interface:
+ - compare results of baseline sanity checks with expected results
+
+-# builds a more complete test suite:
+ - existing testing/examples/ look like a great start
+ - all targets should be tested fully and for all capabilities
+ - we do NOT want a "lowest common denominator" test suite
+ - ... but can we start with one to get going?
+ - probably requires one test configuration file per board/target
+ - modularization can occur here, just like with targets/boards/chips
+ - coverage can increase over time, building up bundles of tests
+
+-# add new 'smoketest' Makefile target:
+ - calls 'make check' (and the smoketest app)
+ - gather inputs and output into a report file
+
+@subsection thelisttestreports Test Feedback Tools
+
+These ideas were first introduced here:
+ https://lists.berlios.de/pipermail/openocd-development/2009-May/006358.html
+
+- provide report submission scripts for e-mail and web forms
+- add new Makefile targets to post the report:
+ - 'checkreportsend' -- send to list via e-mail (via sendmail)
+ - 'checkreportpost' -- send web form (via curl or other script)
+
+@subsection thelisttestgenerichw Generic Hardware Tester
+
+- implement VHDL to use for FPGA-based JTAG TAP testing device
+- develop test suite that utilizes this testing device
+
+@section thelistautotools Autotools Build System
+
+- investigate fixes to permit the use of -Wshadow
+- eliminate sources of confusion in @c boostrap script:
+ -# Make @c bootstrap call 'configure --enable-maintainer-mode <opts>'?
+ -# Add @c buildstrap script to assist with boostrap and configure steps.
+- automatically build tool-chains required for cross-compiling
+ - produce mingw32, arm-elf, others using in-tree scripts
+ - build all required target code from sources
+- make JTAG and USB debug output a run-time configuration option
+
+@section thelistarchitecture Architectural Tasks
+
+The following architectural tasks need to be accomplished and should be
+fairly easy to complete:
+
+- factor code to eliminate duplicated functionality
+- overhaul use of types to improve 32/64-bit portability
+- rewrite code that uses casts to access 16-bit and larger types
+ from unaligned memory addresses
+- libopenocd support: @par
+ https://lists.berlios.de/pipermail/openocd-development/2009-May/006405.html
+- review and clean up interface/target/flash APIs
+
+The following strategic tasks will require ambition, knowledge, and time
+to complete:
+
+- Allow N:M:P mapping of servers, targets, and interfaces
+- loadable module support for interface/target/flash drivers
+
+@section thelistadmin Administrative Tasks
+
+- Develop "style" guidelines for committing to Subversion
+- Develop milestone and release guidelines.
