For passing the board revision using the pass through u-boot is probably the best long term solution. U-boot can read the ATAGs from nolo and modify the .dtb for the revision information.

But I do not know if address of ATAG > structure is available there... Are there other ATAGs needed beyond the ATAG_REVISION?
