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.
