| Peter Tyser | 5fc56b9 | 2009-01-30 16:36:40 -0600 | [diff] [blame] | 1 | The following is a list of files and features that are going to be |
| 2 | removed from the U-Boot source tree. Every entry should contain what |
| 3 | exactly is going away, when it will be gone, why it is being removed, |
| Wolfgang Denk | d483a22 | 2010-09-29 11:25:55 +0200 | [diff] [blame^] | 4 | and who is going to be doing the work. When the feature is removed |
| Peter Tyser | 5fc56b9 | 2009-01-30 16:36:40 -0600 | [diff] [blame] | 5 | from U-Boot, its corresponding entry should also be removed from this |
| 6 | file. |

| Wolfgang Denk | d483a22 | 2010-09-29 11:25:55 +0200 | [diff] [blame^] | 9 | What: CONFIG_SYS_ARM_WITHOUT_RELOC option |
| 10 | When: After Release 2011.03 |
| 11 | |
| 12 | Why: The implementation of U-Boot for the ARM architecture has |
| 13 | been reworked to support relocation. This allows to |
| 14 | efficiently use the same U-Boot binary image on systems with |
| 15 | different RAM sizes, and brings the implementation much more |
| 16 | in line with the code used for example on Power Architecture |
| 17 | systems (eventually allowing to merge into common code). This |
| 18 | seems especailly interesting now that ARM is getting Device |
| 19 | Tree support as well. |
| 20 | |
| 21 | All ARM boards need to be adapted to this new code, which |
| 22 | requires testing on the actual hardware, so this is a task |
| 23 | for the respective board maintainers or other users. |
| 24 | |
| 25 | Please see the commit message of commit f1d2b31 for details: |
| 26 | |
| 27 | http://git.denx.de/?p=u-boot.git;a=commit;h=f1d2b31 |
| 28 | |
| 29 | Support for CONFIG_SYS_ARM_WITHOUT_RELOC will be removed |
| 30 | after release v2011.03; all boards that have not been |
| 31 | converted by then, i. e. that are still broken then, are |
| 32 | considered unmaintained and without interest for the |
| 33 | community and will be removed as well. |

| Ben Warren | c404cc5 | 2009-04-28 17:04:51 -0700 | [diff] [blame] | 37 | What: CONFIG_NET_MULTI option |
| 38 | When: Release 2009-11 |
| 39 | |
| 40 | Why: U-boot currently implements two network driver APIs. New drivers with |
| 41 | the older-style implementation have not been accepted for a while, and |
| 42 | this parallel system makes the code confusing and hard to augment. |
| 43 | |
| 44 | All existing in-tree boards will be converted to use CONFIG_NET_MULTI |
| 45 | over the span of two releases (2009-07 and 2009-09). |
| 46 | In the 2009-11 release, all code that is compiled when CONFIG_NET_MULTI |
| 47 | is not set will be removed, and all references to CONFIG_NET_MULTI |
| 48 | will be removed, effectively making it the only API. This should |
| 49 | provide ample time for out-of-tree users to adjust, and for tools on |
| 50 | all architectures to be made to work with weak functions. |

| Wolfgang Denk | 78237df | 2009-04-02 17:31:09 +0200 | [diff] [blame] | 56 | What: GPL cleanup |
| 57 | When: August 2009 |
| 58 | Why: Over time, a couple of files have sneaked in into the U-Boot |
| 59 | source code that are either missing a valid GPL license |
| 60 | header or that carry a license that is incompatible with the |
| 61 | GPL. |
| 62 | Such files shall be removed from the U-Boot source tree. |
| 63 | See http://www.denx.de/wiki/pub/U-Boot/TaskGplCleanup/u-boot-1.1.2-files |
| 64 | for an old and probably incomplete list of such files. |
