| The following is a list of files and features that are going to be |
| removed from the U-Boot source tree. Every entry should contain what |
| exactly is going away, when it will be gone, why it is being removed, |
| and who is going to be doing the work. When the feature is removed |
| from U-Boot, its corresponding entry should also be removed from this |
| file. |

| What: CONFIG_SYS_ARM_WITHOUT_RELOC option |
| When: After Release 2011.03 |
| |
| Why: The implementation of U-Boot for the ARM architecture has |
| been reworked to support relocation. This allows to |
| efficiently use the same U-Boot binary image on systems with |
| different RAM sizes, and brings the implementation much more |
| in line with the code used for example on Power Architecture |
| systems (eventually allowing to merge into common code). This |
| seems especailly interesting now that ARM is getting Device |
| Tree support as well. |
| |
| All ARM boards need to be adapted to this new code, which |
| requires testing on the actual hardware, so this is a task |
| for the respective board maintainers or other users. |
| |
| Please see the commit message of commit f1d2b31 for details: |
| |
| http://git.denx.de/?p=u-boot.git;a=commit;h=f1d2b31 |
| |
| Support for CONFIG_SYS_ARM_WITHOUT_RELOC will be removed |
| after release v2011.03; all boards that have not been |
| converted by then, i. e. that are still broken then, are |
| considered unmaintained and without interest for the |
| community and will be removed as well. |
| |
| --------------------------- |
| |
| What: CONFIG_NET_MULTI option |
| When: Release 2009-11 |
| |
| Why: U-boot currently implements two network driver APIs. New drivers with |
| the older-style implementation have not been accepted for a while, and |
| this parallel system makes the code confusing and hard to augment. |
| |
| All existing in-tree boards will be converted to use CONFIG_NET_MULTI |
| over the span of two releases (2009-07 and 2009-09). |
| In the 2009-11 release, all code that is compiled when CONFIG_NET_MULTI |
| is not set will be removed, and all references to CONFIG_NET_MULTI |
| will be removed, effectively making it the only API. This should |
| provide ample time for out-of-tree users to adjust, and for tools on |
| all architectures to be made to work with weak functions. |

| |
| What: GPL cleanup |
| When: August 2009 |
| Why: Over time, a couple of files have sneaked in into the U-Boot |
| source code that are either missing a valid GPL license |
| header or that carry a license that is incompatible with the |
| GPL. |
| Such files shall be removed from the U-Boot source tree. |
| See http://www.denx.de/wiki/pub/U-Boot/TaskGplCleanup/u-boot-1.1.2-files |
| for an old and probably incomplete list of such files. |
