[U-Boot] Help on mem relocation issue when reworking on at91sam9rlek

Hi Reinhard,

I have an issue when I reworked U-Boot for AT91SAM9RL-EK.
When I choose `at91sam9rlek_nandflash', things are quite smooth.
But when I choose `at91sam9rlek_dataflash_cs0', uboot will stop
booting after `relocate_code()'.

Do you have some hints about this? Thanks a lot.

Please see below the U-Boot output,
