/** @page thelist Pending and Open Tasks

This page lists pending and open tasks being considered or worked upon
by the OpenOCD community.


Items with a current patch available should include a link to its
posting on the openocd-developer mailing list archives.

Some items may be in progress, usually indicated by the individual whose
initials in parentheses following it.  A key for decoding these initials
appears after The List.

Most items are open for the taking, but please post to the mailing list
before spending much time working on anything lists here.  The community
may have evolved an idea since it was added here.

Feel free to send patches to add or clarify items on this list, too.

- 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.

    - fix outstanding bugs
  - J-Link driver: (ZW)
    - fix outstanding bugs
    - test with known targets (i.e. working with other interfaces)
    - test compatibility between v6.0 (yellow) and older units (e.g. v5.2)
  - TCP driver:
    - add TCP/IP client and server for remote JTAG interface control
  - Do others need some help?  Probably....

- Other Interfaces
  - SVF/XSVF:
    - pending tasks??
  - SPI/UART emulation:
    - (ab)use bit-banging JTAG interfaces to emulate SPI/UART
    - allow SPI to program flash, MCUs, etc.
  - SWD

- Target Support:
  - general layer cleanup:
    - https://lists.berlios.de/pipermail/openocd-development/2009-May/006590.html
  - ARM11 improvements (MB?)
    - fix single stepping  (reported by ØH)
    - implement missing functionality (grep FNC_INFO_NOTIMPLEMENTED ...)
  - Cortex A8 support (ML)
    - add target implementation (ML)
    - what else remains to be done?
  - MC1322x support (JW/DE?)
    - integrate and test support from JW (and DE?)
    - get working with a known good interface (i.e. not today's jlink)
  - AT91SAM92xx:
    - improvements for unknown-board-atmel-at91sam9260.cfg (RD)
  - STR9x: (ZW)
    - improvements to str912.cfg to be more general purpose
  - AVR: (SQ)
    - independently verify implementation
    - incrementally improve working prototype in trunk. (SQ)
    - work out how to debug this target
    - AVR debugging protocol.
  - FPGA:
    - improve things (??)
  - Coldfire (suggested by NC)
    - can we draw from the BDM project?  @par
      http://bdm.sourceforge.net/

  - other targets?  (suggestions always welcome)

- CFI:
  - finish implementing bus width/chip width handling (suggested by NC)
  - factor vendor-specific code into separate source files
  - add new callback interface for vendor-specific code
  - investigate/implement "thin wrapper" to use eCos CFI drivers (ØH)

- TCL
  - Isolate all TCL command support: 
    - Allow pure C CLI implementations using --disable-builtin-tcl. 
    Ref? How could this be made to work given targets extensive need
    for events, etc.? What about the target library?
    - Allow full TCL support? add --with-tcl=/path/to/installed/tcl
    - Move TCL support in foo.* to foo_tcl.* (other ideas?)

- Debugger Support
  - Keil AGDI interface to OpenOCD (submitted by Dario Vecchio)

- Architectural Upgrades
  - Allow N:M:P mapping of servers, targets, and interfaces
  - loadable module support for interface/target/flash drivers
  - libopenocd support: @par
      https://lists.berlios.de/pipermail/openocd-development/2009-May/006405.html

- Test Suite:
  - implement server unit tests
  - implement JTAG core unit tests
  - implement JTAG interface unit tests
  - implement flash unit tests
  - implement target unit tests

- Test Feedback Tools: @par
      https://lists.berlios.de/pipermail/openocd-development/2009-May/006358.html

  - extend target test script to produce helpful pass/fail output
  - provide results submission script


- Generic Hardware Tester:
  - implement VHDL to use for FPGA-based JTAG TAP testing device
  - develop test suite that utilizes this testing device

- Build Systems (Autotools, CMake, etc.)
  - investigate fixes to permit the use of -Wshadow
  - change bootstrap to call 'configure --enable-maintainer-mode <opts>'?

- Miscellaneous:
  - make JTAG and USB debug output a run-time configuration option
  - review and clean up interface/target/flash APIs 
  - factor code to eliminate duplicated functionality
  - overhaul use of types to improve 32/64-bit portability

- Berlios Admin:
  - use patch tracker? @par
    https://developer.berlios.de/patch/?group_id=4148
  - use bug tracking?  we need something!
