Hi. I also got it working with a single board compilation now.

You are correct that it is the CONFIG_RELOCATABLE that is the issue.
If I select this it works.

I didn't turn it off. It isn't selected by MACH_FREESCALE_MX7_SABRESD
so it gets turned off if only this board is used. It is selected by 6
other boards, which is the reason it works when compiling for all
boards.
