I've finally produced a working u-boot for our board. Thanx to Fabio I did:

- compare the elf files for the NAND build between toolchains, no change.
- flash his mx31pdk NAND flash version to our NAND and it started correctly
- compile mx31pdk_nand_config, flash to NAND, again everything fine.
- compile a NAND flash version for our board and it worked as-well
- test 3 different toolchains and all of them performed equally well.

While I now got a running NAND flash version, I'm still unable to get 
the NOR flash version into gears. The NAND version is significantly 
different, as the NAND-spl loads the u-boot directly to the location in 
RAM that it was linked for.

I compiled 'mx31pdk_config' top-of-tree and it did not start up.

I'm still inclined to say that something is wrong with the NOR flash 
version of the startup code, so I'd like to rephrase my original question:

Is there working version of a 2011 arm uboot (possibly for i.MX31) that 
boots from NOR flash?
