I don't understand; I thought that '#undef' _enabled_ relocation
support. According to doc/README.arm-relocation on u-boot./next:

To compile a board without relocation, define CONFIG_SYS_ARM_WITHOUT_RELOC
This possibility will removed!! So please fix your board to compile without
CONFIG_SYS_ARM_WITHOUT_RELOC defined!!!

But I did test relocation on this board with Heiko and it is working
as-is on d70d8ccc200db8c16a6654cb726c3d74b6640b32 of u-boot/next; we
found that 97003756249bd790910417eb66f0039bbf06a02c made it work.

I can confirm that -- as you suggest -- the following applied to u-boot/next
diff --git a/include/configs/da850evm.h b/include/configs/da850evm.h
index d02b196..e0a3bae 100644
--- a/include/configs/da850evm.h
+++ b/include/configs/da850evm.h

 #endif

 /* additions for new relocation code, must added to all boards */
-#undef CONFIG_SYS_ARM_WITHOUT_RELOC /* This board is tested with
relocation support */
 #define CONFIG_SYS_SDRAM_BASE          0xc0000000
 #define CONFIG_SYS_INIT_SP_ADDR                (CONFIG_SYS_SDRAM_BASE
+ 0x1000 - /* Fix this */ \
                                        CONFIG_SYS_GBL_DATA_SIZE)

also works on da850evm. But isn't this disabling the recently added
relocation support?

Best Regards,
Ben Gardiner
