Ups, you are right, fix this.

Hmm.. think you are right, I try this, thanks.

Ok.

Hmm.. instead we should remove in arch/arm/include/asm/config.h

  24 #if defined(CONFIG_SYS_ARM_WITHOUT_RELOC)
  25 /* Relocation to SDRAM works on all ARM boards */
  26 #define CONFIG_RELOC_FIXUP_WORKS
  27 #endif

this #if defined(CONFIG_SYS_ARM_WITHOUT_RELOC) ... #endif

And remove for all arm board, which now define CONFIG_RELOC_FIXUP_WORKS
this in the config file. If you are OK with that, I can make such a
patch.

bye,
Heiko
