Hello,

due to memory limitations in the SRAM of the i.MX6S in SPL we have not used the device tree. Have the restrictions been removed in the meantime? We need a single binary for the i.MX6 q/d/dl/s variants of our system on module.

I think this patch breaks the board support for our module.

regards,
Ludwig Zenz
