Drop support for CONFIG_SYS_ARM_WITHOUT_RELOC
When this define was introduced, the idea was to provide a soft migration path for ARM boards to get adapted to the new relocation support. However, other recent changes led to a different implementation (ELF relocation), where this no longer works. By now CONFIG_SYS_ARM_WITHOUT_RELOC does not only not help any more, but it actually hurts because it obfuscates the actual code by sprinkling it with lots of dead and non-working debris. So let's make a clean cut and drop CONFIG_SYS_ARM_WITHOUT_RELOC. Signed-off-by: Wolfgang Denk <wd@denx.de> Tested-by: Heiko Schocher <hs@denx.de> Tested-by: Reinhard Meyer <u-boot@emk-elektronik.de>

-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.
