/** @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.

- Other Interfaces
  - SVF/XSVF:
    - pending tasks??
  - SPI/UART emulation:
    - (ab)use bit-banging JTAG interfaces to emulate SPI/UART

  - 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)

    - 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

- TCL
  - mem2array bugs:
    - Report: https://lists.berlios.de/pipermail/openocd-development/2009-May/006459.html
  - Isolate all TCL command support: 
    - Allow pure C CLI implementations using --disable-builtin-tcl
    - Allow full TCL support? add --with-tcl=/path/to/installed/tcl
    - Move TCL support in foo.* to foo_tcl.* (other ideas?)
