  1. The following is a list of files and features that are going to be
    2. 

  2. removed from the U-Boot source tree.  Every entry should contain what
    3. 

  3. exactly is going away, when it will be gone, why it is being removed,
    4. 

  4. and who is going to be doing the work.	When the feature is removed
    5. 

  5. from U-Boot, its corresponding entry should also be removed from this
    6. 

  6. file.
    7. 

  7. 

  8. ---------------------------
    9. 

  9. 

  10. What:	boards with xxx_config targets in top level Makefile
    11. 

  11. When:	Release v2012.03
    12. 

  12. 

  13. Why:	We have a boards.cfg file which the vast majority of boards have
    14. 

  14. 	converted over to.  Boards that still manually run mkconfig in the
    15. 

  15. 	top level Makefile are either dead, or the maintainer doesn't care,
    16. 

  16. 	or they are doing something weird/wrong that should be fixed in a
    17. 

  17. 	different way, or they need to extend boards.cfg syntax (unlikely).
    18. 

  18. 

  19. 	In any case, if no one cares about these boards to figure out how
    20. 

  20. 	to make boards.cfg work, then we'll just punt them.
    21. 

  21. 

  22. Who:	Mike Frysinger <vapier@gentoo.org>
    23. 

  23. 

  24. ---------------------------
    25. 

  25. 

  26. What:	CONFIG_NET_MULTI option
    27. 

  27. When:	Release 2009-11
    28. 

  28. 

  29. Why:	U-boot currently implements two network driver APIs.  New drivers with
    30. 

  30. 	the older-style implementation have not been accepted for a while, and
    31. 

  31. 	this parallel system makes the code confusing and hard to augment.
    32. 

  32. 

  33. 	All existing in-tree boards will be converted to use CONFIG_NET_MULTI
    34. 

  34. 	over the span of two releases (2009-07 and 2009-09).
    35. 

  35. 	In the 2009-11 release, all code that is compiled when CONFIG_NET_MULTI
    36. 

  36. 	is not set will be removed, and all references to CONFIG_NET_MULTI
    37. 

  37. 	will be removed, effectively making it the only API.  This should
    38. 

  38. 	provide ample time for out-of-tree users to adjust, and for tools on
    39. 

  39. 	all architectures to be made to work with weak functions.
    40.

  41. Who:	Ben Warren <biggerbadderben@gmail.com>
    42. 

  42. 

  43. ---------------------------
    44. 

  44. 

  45. What:	GPL cleanup
    46. 

  46. When:	August 2009
    47. 

  47. Why:	Over time, a couple of files have sneaked in into the U-Boot
    48. 

  48. 	source code that are either missing a valid GPL license
    49. 

  49. 	header or that carry a license that is incompatible with the
    50. 

  50. 	GPL.
    51. 

  51. 	Such files shall be removed from the U-Boot source tree.
    52. 

  52. 	See http://www.denx.de/wiki/pub/U-Boot/TaskGplCleanup/u-boot-1.1.2-files
    53. 

  53. 	for an old and probably incomplete list of such files.
    54. 

  54. 

  55. Who:	Wolfgang Denk <wd@denx.de> and board maintainers
    56.
