Actually, this is already clearly stated against DEBUG_LL:

          Note that selecting this option will limit the kernel to a single
          UART definition, as specified below. Attempting to boot the kernel
          image on a different platform *will not work*, so this option should
          not be enabled for kernels that are intended to be portable.

and since EARLY_PRINTK depends on DEBUG_LL... I guess people don't
read help texts anymore.
