I've made some progress. Yes, the TZIC is not being set up properly. This is because the system and rev information is not being put into the ATAG that is passed to the Linux kernel. What is added is " #define CONFIG_REVISION_TAG 1" in the config file but then "get_board_rev" needs to be implemented. I am going to take what is in FSL u-boot for that. I have to get going now but hope to finish this on Monday.
Good news! This function can easily be added locally to your board init file. I don't think that mainline U-Boot should be changed for that since it is an issue in FSL's Linux that relies on the revision tag instead of extracting itself the revision information from the hardware.

I think we should change U-boot mainline for mx51evk in this case.
We do pass get_board_rev() on mx53loco and mx6qsabrelite boards in order to allow booting a FSL kernel too.
By doing this we allow people that use the old kernel to run a mainline U-boot.
Thanks,

OK, then Greg, please make this patch after your Monday's tests.
Best regards, Benoît
